The Free Translation Project is +a way to get maintainers of free software, translators, and users all +together, so that will gradually become able to speak many languages. +A few packages already provide translations for their messages. + + If you found this `ABOUT-NLS' file inside a distribution, you may +assume that the distributed package does use GNU `gettext' internally, +itself available at your nearest GNU archive site. But you do _not_ +need to install GNU `gettext' prior to configuring, installing or using +this package with messages translated. + + Installers will find here some useful hints. These notes also +explain how users should proceed for getting the programs to use the +available translations. They tell how people wanting to contribute and +work at translations should contact the appropriate team. + + When reporting bugs in the `intl/' directory or bugs which may be +related to internationalization, you should tell about the version of +`gettext' which is used. The information can be found in the +`intl/VERSION' file, in internationalized packages. + +Quick configuration advice +========================== + +If you want to exploit the full power of internationalization, you +should configure it using + + ./configure --with-included-gettext + +to force usage of internationalizing routines provided within this +package, despite the existence of internationalizing capabilities in the +operating system where this package is being installed. So far, only +the `gettext' implementation in the GNU C library version 2 provides as +many features (such as locale alias, message inheritance, automatic +charset conversion or plural form handling) as the implementation here. +It is also not possible to offer this additional functionality on top +of a `catgets' implementation. Future versions of GNU `gettext' will +very likely convey even more functionality. So it might be a good idea +to change to GNU `gettext' as soon as possible. + + So you need _not_ provide this option if you are using GNU libc 2 or +you have installed a recent copy of the GNU gettext package with the +included `libintl'. + +INSTALL Matters +=============== + +Some packages are "localizable" when properly installed; the programs +they contain can be made to speak your own native language. Most such +packages use GNU `gettext'. Other packages have their own ways to +internationalization, predating GNU `gettext'. + + By default, this package will be installed to allow translation of +messages. It will automatically detect whether the system already +provides the GNU `gettext' functions. If not, the GNU `gettext' own +library will be used. This library is wholly contained within this +package, usually in the `intl/' subdirectory, so prior installation of +the GNU `gettext' package is _not_ required. Installers may use +special options at configuration time for changing the default +behaviour. The commands: + + ./configure --with-included-gettext + ./configure --disable-nls + +will respectively bypass any pre-existing `gettext' to use the +internationalizing routines provided within this package, or else, +_totally_ disable translation of messages. + + When you already have GNU `gettext' installed on your system and run +configure without an option for your new package, `configure' will +probably detect the previously built and installed `libintl.a' file and +will decide to use this. This might be not what is desirable. You +should use the more recent version of the GNU `gettext' library. I.e. +if the file `intl/VERSION' shows that the library which comes with this +package is more recent, you should use + + ./configure --with-included-gettext + +to prevent auto-detection. + + The configuration process will not test for the `catgets' function +and therefore it will not be used. The reason is that even an +emulation of `gettext' on top of `catgets' could not provide all the +extensions of the GNU `gettext' library. + + Internationalized packages have usually many `po/LL.po' files, where +LL gives an ISO 639 two-letter code identifying the language. Unless +translations have been forbidden at `configure' time by using the +`--disable-nls' switch, all available translations are installed +together with the package. However, the environment variable `LINGUAS' +may be set, prior to configuration, to limit the installed set. +`LINGUAS' should then contain a space separated list of two-letter +codes, stating which languages are allowed. + +Using This Package +================== + +As a user, if your language has been installed for this package, you +only have to set the `LANG' environment variable to the appropriate +`LL_CC' combination. Here `LL' is an ISO 639 two-letter language code, +and `CC' is an ISO 3166 two-letter country code. For example, let's +suppose that you speak German and live in Germany. At the shell +prompt, merely execute `setenv LANG de_DE' (in `csh'), +`export LANG; LANG=de_DE' (in `sh') or `export LANG=de_DE' (in `bash'). +This can be done from your `.login' or `.profile' file, once and for +all. + + You might think that the country code specification is redundant. +But in fact, some languages have dialects in different countries. For +example, `de_AT' is used for Austria, and `pt_BR' for Brazil. The +country code serves to distinguish the dialects. + + The locale naming convention of `LL_CC', with `LL' denoting the +language and `CC' denoting the country, is the one use on systems based +on GNU libc. On other systems, some variations of this scheme are +used, such as `LL' or `LL_CC.ENCODING'. You can get the list of +locales supported by your system for your country by running the command +`locale -a | grep '^LL''. + + Not all programs have translations for all languages. By default, an +English message is shown in place of a nonexistent translation. If you +understand other languages, you can set up a priority list of languages. +This is done through a different environment variable, called +`LANGUAGE'. GNU `gettext' gives preference to `LANGUAGE' over `LANG' +for the purpose of message handling, but you still need to have `LANG' +set to the primary language; this is required by other parts of the +system libraries. For example, some Swedish users who would rather +read translations in German than English for when Swedish is not +available, set `LANGUAGE' to `sv:de' while leaving `LANG' to `sv_SE'. + + Special advice for Norwegian users: The language code for Norwegian +bokma*l changed from `no' to `nb' recently (in 2003). During the +transition period, while some message catalogs for this language are +installed under `nb' and some older ones under `no', it's recommended +for Norwegian users to set `LANGUAGE' to `nb:no' so that both newer and +older translations are used. + + In the `LANGUAGE' environment variable, but not in the `LANG' +environment variable, `LL_CC' combinations can be abbreviated as `LL' +to denote the language's main dialect. For example, `de' is equivalent +to `de_DE' (German as spoken in Germany), and `pt' to `pt_PT' +(Portuguese as spoken in Portugal) in this context. + +Translating Teams +================= + +For the Free Translation Project to be a success, we need interested +people who like their own language and write it well, and who are also +able to synergize with other translators speaking the same language. +Each translation team has its own mailing list. The up-to-date list of +teams can be found at the Free Translation Project's homepage, +`http://www.iro.umontreal.ca/contrib/po/HTML/', in the "National teams" +area. + + If you'd like to volunteer to _work_ at translating messages, you +should become a member of the translating team for your own language. +The subscribing address is _not_ the same as the list itself, it has +`-request' appended. For example, speakers of Swedish can send a +message to `sv-request@li.org', having this message body: + + subscribe + + Keep in mind that team members are expected to participate +_actively_ in translations, or at solving translational difficulties, +rather than merely lurking around. If your team does not exist yet and +you want to start one, or if you are unsure about what to do or how to +get started, please write to `translation@iro.umontreal.ca' to reach the +coordinator for all translator teams. + + The English team is special. It works at improving and uniformizing +the terminology in use. Proven linguistic skill are praised more than +programming skill, here. + +Available Packages +================== + +Languages are not equally supported in all packages. The following +matrix shows the current state of internationalization, as of January +2004.

By contrast, +the GNU General Public License is intended to guarantee your freedom to +share and change all versions of a program--to make sure it remains free +software for all its users. We, the Free Software Foundation, use the +GNU General Public License for most of our software; it applies also to +any other work released this way by its authors. You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +them if you wish), that you receive source code or can get it if you +want it, that you can change the software or use pieces of it in new +free programs, and that you know you can do these things. + + To protect your rights, we need to prevent others from denying you +these rights or asking you to surrender the rights. Therefore, you have +certain responsibilities if you distribute copies of the software, or if +you modify it: responsibilities to respect the freedom of others. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must pass on to the recipients the same +freedoms that you received. You must make sure that they, too, receive +or can get the source code. And you must show them these terms so they +know their rights. + + Developers that use the GNU GPL protect your rights with two steps: +(1) assert copyright on the software, and (2) offer you this License +giving you legal permission to copy, distribute and/or modify it. + + For the developers' and authors' protection, the GPL clearly explains +that there is no warranty for this free software. For both users' and +authors' sake, the GPL requires that modified versions be marked as +changed, so that their problems will not be attributed erroneously to +authors of previous versions. + + Some devices are designed to deny users access to install or run +modified versions of the software inside them, although the manufacturer +can do so. This is fundamentally incompatible with the aim of +protecting users' freedom to change the software. The systematic +pattern of such abuse occurs in the area of products for individuals to +use, which is precisely where it is most unacceptable. Therefore, we +have designed this version of the GPL to prohibit the practice for those +products. If such problems arise substantially in other domains, we +stand ready to extend this provision to those domains in future versions +of the GPL, as needed to protect the freedom of users. + + Finally, every program is threatened constantly by software patents. +States should not allow patents to restrict development and use of +software on general-purpose computers, but in those that do, we wish to +avoid the special danger that patents applied to a free program could +make it effectively proprietary. To prevent this, the GPL assures that +patents cannot be used to render the program non-free. + + The precise terms and conditions for copying, distribution and +modification follow. + + TERMS AND CONDITIONS + + 0. Definitions. + + "This License" refers to version 3 of the GNU General Public License. + + "Copyright" also means copyright-like laws that apply to other kinds of +works, such as semiconductor masks. + + "The Program" refers to any copyrightable work licensed under this +License. Each licensee is addressed as "you". "Licensees" and +"recipients" may be individuals or organizations. + + To "modify" a work means to copy from or adapt all or part of the work +in a fashion requiring copyright permission, other than the making of an +exact copy. The resulting work is called a "modified version" of the +earlier work or a work "based on" the earlier work. + + A "covered work" means either the unmodified Program or a work based +on the Program. + + To "propagate" a work means to do anything with it that, without +permission, would make you directly or secondarily liable for +infringement under applicable copyright law, except executing it on a +computer or modifying a private copy. Propagation includes copying, +distribution (with or without modification), making available to the +public, and in some countries other activities as well. + + To "convey" a work means any kind of propagation that enables other +parties to make or receive copies. Mere interaction with a user through +a computer network, with no transfer of a copy, is not conveying. + + An interactive user interface displays "Appropriate Legal Notices" +to the extent that it includes a convenient and prominently visible +feature that (1) displays an appropriate copyright notice, and (2) +tells the user that there is no warranty for the work (except to the +extent that warranties are provided), that licensees may convey the +work under this License, and how to view a copy of this License. If +the interface presents a list of user commands or options, such as a +menu, a prominent item in the list meets this criterion. + + 1. Source Code. + + The "source code" for a work means the preferred form of the work +for making modifications to it. "Object code" means any non-source +form of a work. + + A "Standard Interface" means an interface that either is an official +standard defined by a recognized standards body, or, in the case of +interfaces specified for a particular programming language, one that +is widely used among developers working in that language. + + The "System Libraries" of an executable work include anything, other +than the work as a whole, that (a) is included in the normal form of +packaging a Major Component, but which is not part of that Major +Component, and (b) serves only to enable use of the work with that +Major Component, or to implement a Standard Interface for which an +implementation is available to the public in source code form. A +"Major Component", in this context, means a major essential component +(kernel, window system, and so on) of the specific operating system +(if any) on which the executable work runs, or a compiler used to +produce the work, or an object code interpreter used to run it. + + The "Corresponding Source" for a work in object code form means all +the source code needed to generate, install, and (for an executable +work) run the object code and to modify the work, including scripts to +control those activities. However, it does not include the work's +System Libraries, or general-purpose tools or generally available free +programs which are used unmodified in performing those activities but +which are not part of the work. For example, Corresponding Source +includes interface definition files associated with source files for +the work, and the source code for shared libraries and dynamically +linked subprograms that the work is specifically designed to require, +such as by intimate data communication or control flow between those +subprograms and other parts of the work. + + The Corresponding Source need not include anything that users +can regenerate automatically from other parts of the Corresponding +Source. + + The Corresponding Source for a work in source code form is that +same work. + + 2. Basic Permissions. + + All rights granted under this License are granted for the term of +copyright on the Program, and are irrevocable provided the stated +conditions are met. This License explicitly affirms your unlimited +permission to run the unmodified Program. The output from running a +covered work is covered by this License only if the output, given its +content, constitutes a covered work. This License acknowledges your +rights of fair use or other equivalent, as provided by copyright law. + + You may make, run and propagate covered works that you do not +convey, without conditions so long as your license otherwise remains +in force. You may convey covered works to others for the sole purpose +of having them make modifications exclusively for you, or provide you +with facilities for running those works, provided that you comply with +the terms of this License in conveying all material for which you do +not control copyright. Those thus making or running the covered works +for you must do so exclusively on your behalf, under your direction +and control, on terms that prohibit them from making any copies of +your copyrighted material outside their relationship with you. + + Conveying under any other circumstances is permitted solely under +the conditions stated below. Sublicensing is not allowed; section 10 +makes it unnecessary. + + 3. Protecting Users' Legal Rights From Anti-Circumvention Law. + + No covered work shall be deemed part of an effective technological +measure under any applicable law fulfilling obligations under article +11 of the WIPO copyright treaty adopted on 20 December 1996, or +similar laws prohibiting or restricting circumvention of such +measures. + + When you convey a covered work, you waive any legal power to forbid +circumvention of technological measures to the extent such circumvention +is effected by exercising rights under this License with respect to +the covered work, and you disclaim any intention to limit operation or +modification of the work as a means of enforcing, against the work's +users, your or third parties' legal rights to forbid circumvention of +technological measures. + + 4. Conveying Verbatim Copies. + + You may convey verbatim copies of the Program's source code as you +receive it, in any medium, provided that you conspicuously and +appropriately publish on each copy an appropriate copyright notice; +keep intact all notices stating that this License and any +non-permissive terms added in accord with section 7 apply to the code; +keep intact all notices of the absence of any warranty; and give all +recipients a copy of this License along with the Program. + + You may charge any price or no price for each copy that you convey, +and you may offer support or warranty protection for a fee. + + 5. Conveying Modified Source Versions. + + You may convey a work based on the Program, or the modifications to +produce it from the Program, in the form of source code under the +terms of section 4, provided that you also meet all of these conditions: + + a) The work must carry prominent notices stating that you modified + it, and giving a relevant date. + + b) The work must carry prominent notices stating that it is + released under this License and any conditions added under section + 7. This requirement modifies the requirement in section 4 to + "keep intact all notices". + + c) You must license the entire work, as a whole, under this + License to anyone who comes into possession of a copy. This + License will therefore apply, along with any applicable section 7 + additional terms, to the whole of the work, and all its parts, + regardless of how they are packaged. This License gives no + permission to license the work in any other way, but it does not + invalidate such permission if you have separately received it. + + d) If the work has interactive user interfaces, each must display + Appropriate Legal Notices; however, if the Program has interactive + interfaces that do not display Appropriate Legal Notices, your + work need not make them do so. + + A compilation of a covered work with other separate and independent +works, which are not by their nature extensions of the covered work, +and which are not combined with it such as to form a larger program, +in or on a volume of a storage or distribution medium, is called an +"aggregate" if the compilation and its resulting copyright are not +used to limit the access or legal rights of the compilation's users +beyond what the individual works permit. Inclusion of a covered work +in an aggregate does not cause this License to apply to the other +parts of the aggregate. + + 6. Conveying Non-Source Forms. + + You may convey a covered work in object code form under the terms +of sections 4 and 5, provided that you also convey the +machine-readable Corresponding Source under the terms of this License, +in one of these ways: + + a) Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by the + Corresponding Source fixed on a durable physical medium + customarily used for software interchange. + + b) Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by a + written offer, valid for at least three years and valid for as + long as you offer spare parts or customer support for that product + model, to give anyone who possesses the object code either (1) a + copy of the Corresponding Source for all the software in the + product that is covered by this License, on a durable physical + medium customarily used for software interchange, for a price no + more than your reasonable cost of physically performing this + conveying of source, or (2) access to copy the + Corresponding Source from a network server at no charge. + + c) Convey individual copies of the object code with a copy of the + written offer to provide the Corresponding Source. This + alternative is allowed only occasionally and noncommercially, and + only if you received the object code with such an offer, in accord + with subsection 6b. + + d) Convey the object code by offering access from a designated + place (gratis or for a charge), and offer equivalent access to the + Corresponding Source in the same way through the same place at no + further charge. You need not require recipients to copy the + Corresponding Source along with the object code. If the place to + copy the object code is a network server, the Corresponding Source + may be on a different server (operated by you or a third party) + that supports equivalent copying facilities, provided you maintain + clear directions next to the object code saying where to find the + Corresponding Source. Regardless of what server hosts the + Corresponding Source, you remain obligated to ensure that it is + available for as long as needed to satisfy these requirements. + + e) Convey the object code using peer-to-peer transmission, provided + you inform other peers where the object code and Corresponding + Source of the work are being offered to the general public at no + charge under subsection 6d. + + A separable portion of the object code, whose source code is excluded +from the Corresponding Source as a System Library, need not be +included in conveying the object code work. + + A "User Product" is either (1) a "consumer product", which means any +tangible personal property which is normally used for personal, family, +or household purposes, or (2) anything designed or sold for incorporation +into a dwelling. In determining whether a product is a consumer product, +doubtful cases shall be resolved in favor of coverage. For a particular +product received by a particular user, "normally used" refers to a +typical or common use of that class of product, regardless of the status +of the particular user or of the way in which the particular user +actually uses, or expects or is expected to use, the product. A product +is a consumer product regardless of whether the product has substantial +commercial, industrial or non-consumer uses, unless such uses represent +the only significant mode of use of the product. + + "Installation Information" for a User Product means any methods, +procedures, authorization keys, or other information required to install +and execute modified versions of a covered work in that User Product from +a modified version of its Corresponding Source. The information must +suffice to ensure that the continued functioning of the modified object +code is in no case prevented or interfered with solely because +modification has been made. + + If you convey an object code work under this section in, or with, or +specifically for use in, a User Product, and the conveying occurs as +part of a transaction in which the right of possession and use of the +User Product is transferred to the recipient in perpetuity or for a +fixed term (regardless of how the transaction is characterized), the +Corresponding Source conveyed under this section must be accompanied +by the Installation Information. But this requirement does not apply +if neither you nor any third party retains the ability to install +modified object code on the User Product (for example, the work has +been installed in ROM). + + The requirement to provide Installation Information does not include a +requirement to continue to provide support service, warranty, or updates +for a work that has been modified or installed by the recipient, or for +the User Product in which it has been modified or installed. Access to a +network may be denied when the modification itself materially and +adversely affects the operation of the network or violates the rules and +protocols for communication across the network. + + Corresponding Source conveyed, and Installation Information provided, +in accord with this section must be in a format that is publicly +documented (and with an implementation available to the public in +source code form), and must require no special password or key for +unpacking, reading or copying. + + 7. Additional Terms. + + "Additional permissions" are terms that supplement the terms of this +License by making exceptions from one or more of its conditions. +Additional permissions that are applicable to the entire Program shall +be treated as though they were included in this License, to the extent +that they are valid under applicable law. If additional permissions +apply only to part of the Program, that part may be used separately +under those permissions, but the entire Program remains governed by +this License without regard to the additional permissions. + + When you convey a copy of a covered work, you may at your option +remove any additional permissions from that copy, or from any part of +it. (Additional permissions may be written to require their own +removal in certain cases when you modify the work.) You may place +additional permissions on material, added by you to a covered work, +for which you have or can give appropriate copyright permission. + + Notwithstanding any other provision of this License, for material you +add to a covered work, you may (if authorized by the copyright holders of +that material) supplement the terms of this License with terms: + + a) Disclaiming warranty or limiting liability differently from the + terms of sections 15 and 16 of this License; or + + b) Requiring preservation of specified reasonable legal notices or + author attributions in that material or in the Appropriate Legal + Notices displayed by works containing it; or + + c) Prohibiting misrepresentation of the origin of that material, or + requiring that modified versions of such material be marked in + reasonable ways as different from the original version; or + + d) Limiting the use for publicity purposes of names of licensors or + authors of the material; or + + e) Declining to grant rights under trademark law for use of some + trade names, trademarks, or service marks; or + + f) Requiring indemnification of licensors and authors of that + material by anyone who conveys the material (or modified versions of + it) with contractual assumptions of liability to the recipient, for + any liability that these contractual assumptions directly impose on + those licensors and authors. + + All other non-permissive additional terms are considered "further +restrictions" within the meaning of section 10. If the Program as you +received it, or any part of it, contains a notice stating that it is +governed by this License along with a term that is a further +restriction, you may remove that term. If a license document contains +a further restriction but permits relicensing or conveying under this +License, you may add to a covered work material governed by the terms +of that license document, provided that the further restriction does +not survive such relicensing or conveying. + + If you add terms to a covered work in accord with this section, you +must place, in the relevant source files, a statement of the +additional terms that apply to those files, or a notice indicating +where to find the applicable terms. + + Additional terms, permissive or non-permissive, may be stated in the +form of a separately written license, or stated as exceptions; +the above requirements apply either way. + + 8. Termination. + + You may not propagate or modify a covered work except as expressly +provided under this License. Any attempt otherwise to propagate or +modify it is void, and will automatically terminate your rights under +this License (including any patent licenses granted under the third +paragraph of section 11). + + However, if you cease all violation of this License, then your +license from a particular copyright holder is reinstated (a) +provisionally, unless and until the copyright holder explicitly and +finally terminates your license, and (b) permanently, if the copyright +holder fails to notify you of the violation by some reasonable means +prior to 60 days after the cessation. + + Moreover, your license from a particular copyright holder is +reinstated permanently if the copyright holder notifies you of the +violation by some reasonable means, this is the first time you have +received notice of violation of this License (for any work) from that +copyright holder, and you cure the violation prior to 30 days after +your receipt of the notice. + + Termination of your rights under this section does not terminate the +licenses of parties who have received copies or rights from you under +this License. If your rights have been terminated and not permanently +reinstated, you do not qualify to receive new licenses for the same +material under section 10. + + 9. Acceptance Not Required for Having Copies. + + You are not required to accept this License in order to receive or +run a copy of the Program. Ancillary propagation of a covered work +occurring solely as a consequence of using peer-to-peer transmission +to receive a copy likewise does not require acceptance. However, +nothing other than this License grants you permission to propagate or +modify any covered work. These actions infringe copyright if you do +not accept this License. Therefore, by modifying or propagating a +covered work, you indicate your acceptance of this License to do so. + + 10. Automatic Licensing of Downstream Recipients. + + Each time you convey a covered work, the recipient automatically +receives a license from the original licensors, to run, modify and +propagate that work, subject to this License. You are not responsible +for enforcing compliance by third parties with this License. + + An "entity transaction" is a transaction transferring control of an +organization, or substantially all assets of one, or subdividing an +organization, or merging organizations. If propagation of a covered +work results from an entity transaction, each party to that +transaction who receives a copy of the work also receives whatever +licenses to the work the party's predecessor in interest had or could +give under the previous paragraph, plus a right to possession of the +Corresponding Source of the work from the predecessor in interest, if +the predecessor has it or can get it with reasonable efforts. + + You may not impose any further restrictions on the exercise of the +rights granted or affirmed under this License. For example, you may +not impose a license fee, royalty, or other charge for exercise of +rights granted under this License, and you may not initiate litigation +(including a cross-claim or counterclaim in a lawsuit) alleging that +any patent claim is infringed by making, using, selling, offering for +sale, or importing the Program or any portion of it. + + 11. Patents. + + A "contributor" is a copyright holder who authorizes use under this +License of the Program or a work on which the Program is based. The +work thus licensed is called the contributor's "contributor version". + + A contributor's "essential patent claims" are all patent claims +owned or controlled by the contributor, whether already acquired or +hereafter acquired, that would be infringed by some manner, permitted +by this License, of making, using, or selling its contributor version, +but do not include claims that would be infringed only as a +consequence of further modification of the contributor version. For +purposes of this definition, "control" includes the right to grant +patent sublicenses in a manner consistent with the requirements of +this License. + + Each contributor grants you a non-exclusive, worldwide, royalty-free +patent license under the contributor's essential patent claims, to +make, use, sell, offer for sale, import and otherwise run, modify and +propagate the contents of its contributor version. + + In the following three paragraphs, a "patent license" is any express +agreement or commitment, however denominated, not to enforce a patent +(such as an express permission to practice a patent or covenant not to +sue for patent infringement). To "grant" such a patent license to a +party means to make such an agreement or commitment not to enforce a +patent against the party. + + If you convey a covered work, knowingly relying on a patent license, +and the Corresponding Source of the work is not available for anyone +to copy, free of charge and under the terms of this License, through a +publicly available network server or other readily accessible means, +then you must either (1) cause the Corresponding Source to be so +available, or (2) arrange to deprive yourself of the benefit of the +patent license for this particular work, or (3) arrange, in a manner +consistent with the requirements of this License, to extend the patent +license to downstream recipients. "Knowingly relying" means you have +actual knowledge that, but for the patent license, your conveying the +covered work in a country, or your recipient's use of the covered work +in a country, would infringe one or more identifiable patents in that +country that you have reason to believe are valid. + + If, pursuant to or in connection with a single transaction or +arrangement, you convey, or propagate by procuring conveyance of, a +covered work, and grant a patent license to some of the parties +receiving the covered work authorizing them to use, propagate, modify +or convey a specific copy of the covered work, then the patent license +you grant is automatically extended to all recipients of the covered +work and works based on it. + + A patent license is "discriminatory" if it does not include within +the scope of its coverage, prohibits the exercise of, or is +conditioned on the non-exercise of one or more of the rights that are +specifically granted under this License. You may not convey a covered +work if you are a party to an arrangement with a third party that is +in the business of distributing software, under which you make payment +to the third party based on the extent of your activity of conveying +the work, and under which the third party grants, to any of the +parties who would receive the covered work from you, a discriminatory +patent license (a) in connection with copies of the covered work +conveyed by you (or copies made from those copies), or (b) primarily +for and in connection with specific products or compilations that +contain the covered work, unless you entered into that arrangement, +or that patent license was granted, prior to 28 March 2007. + + Nothing in this License shall be construed as excluding or limiting +any implied license or other defenses to infringement that may +otherwise be available to you under applicable patent law. + + 12. No Surrender of Others' Freedom. + + If conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot convey a +covered work so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you may +not convey it at all. For example, if you agree to terms that obligate you +to collect a royalty for further conveying from those to whom you convey +the Program, the only way you could satisfy both those terms and this +License would be to refrain entirely from conveying the Program. + + 13. Use with the GNU Affero General Public License. + + Notwithstanding any other provision of this License, you have +permission to link or combine any covered work with a work licensed +under version 3 of the GNU Affero General Public License into a single +combined work, and to convey the resulting work. The terms of this +License will continue to apply to the part which is the covered work, +but the special requirements of the GNU Affero General Public License, +section 13, concerning interaction through a network will apply to the +combination as such. + + 14. Revised Versions of this License. + + The Free Software Foundation may publish revised and/or new versions of +the GNU General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + + Each version is given a distinguishing version number. If the +Program specifies that a certain numbered version of the GNU General +Public License "or any later version" applies to it, you have the +option of following the terms and conditions either of that numbered +version or of any later version published by the Free Software +Foundation. If the Program does not specify a version number of the +GNU General Public License, you may choose any version ever published +by the Free Software Foundation. + + If the Program specifies that a proxy can decide which future +versions of the GNU General Public License can be used, that proxy's +public statement of acceptance of a version permanently authorizes you +to choose that version for the Program. + + Later license versions may give you additional or different +permissions. However, no additional obligations are imposed on any +author or copyright holder as a result of your choosing to follow a +later version. + + 15. Disclaimer of Warranty. + + THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY +APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT +HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY +OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, +THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR +PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM +IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF +ALL NECESSARY SERVICING, REPAIR OR CORRECTION. + + 16. Limitation of Liability. + + IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS +THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY +GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE +USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF +DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD +PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), +EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF +SUCH DAMAGES. + + 17. Interpretation of Sections 15 and 16. + + If the disclaimer of warranty and limitation of liability provided +above cannot be given local legal effect according to their terms, +reviewing courts shall apply local law that most closely approximates +an absolute waiver of all civil liability in connection with the +Program, unless a warranty or assumption of liability accompanies a +copy of the Program in return for a fee. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +state the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + <one line to give the program's name and a brief idea of what it does.> + Copyright (C) <year> <name of author> + + This program is free software: you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation, either version 3 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the + GNU General Public License for more details. + + You should have received a copy of the GNU General Public License + along with this program. If not, see <http://www.gnu.org/licenses/>. + +Also add information on how to contact you by electronic and paper mail. + + If the program does terminal interaction, make it output a short +notice like this when it starts in an interactive mode: + + <program> Copyright (C) <year> <name of author> + This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. + This is free software, and you are welcome to redistribute it + under certain conditions; type `show c' for details. + +The hypothetical commands `show w' and `show c' should show the appropriate +parts of the General Public License. Of course, your program's commands +might be different; for a GUI interface, you would use an "about box". + + You should also get your employer (if you work as a programmer) or school, +if any, to sign a "copyright disclaimer" for the program, if necessary. +For more information on this, and how to apply and follow the GNU GPL, see +<http://www.gnu.org/licenses/>. + + The GNU General Public License does not permit incorporating your program +into proprietary programs. If your program is a subroutine library, you +may consider it more useful to permit linking proprietary applications with +the library.

In particular, `configure' will look for GTK+ and libglade, +and, if they are present, will generate the appropiate makefiles for +building the `gmixvm' graphical user interface. Upon completion, you +should see a message with the configuration results like the following: + + *** GNU MDK 1.2.1 has been successfully configured. *** + + Type 'make' to build the following utilities: + - mixasm (MIX assembler) + - mixvm (MIX virtual machine, with readline support, + with guile support) + - gmixvm (mixvm GTK+ GUI, with guile support) + - mixguile (the mixvm guile shell) + +where the last lines may be missing if you lack the above mentioned +libraries. + + The next command, `make', will actually build the MDK programs in +the following locations: + + - `mixutils/mixasm' + + - `mixutils/mixvm' + + - `mixgtk/gmixvm' + + - `mixguile/mixguile' + + You can run these programs from within their directories, but I +recommend you to install them in proper locations using `make install' +from a root shell. + +Emacs support +============= + + `mixvm' can be run within an Emacs GUD buffer using the elisp +program `misc/mixvm.el', kindly contributed by {No value for `PHILIP'}. + + `mixvm.el' provides an interface between MDK's `mixvm' and Emacs, +via GUD.

This source code distribution is autoconfiguring and you should be +able to compile it and install it without manual interventions such as +editing Makefiles, configuration files, and so on. These are generic +instructions for people who are not familiar with installing autoconfiguring +software. + +The simplest way to compile this package is to enter the source code +main directory and do the following: + + 1. Configure the source code by typing: + % sh ./configure + + If you're planning to install the package into your home directory + or to a location other than `/usr/local' then add the flag + `--prefix=PATH' to `configure'. For example, if your home directory + is `/home/luser' you can configure the package to install itself there + by invoking: + % sh ./configure --prefix=/home/luser + + While running, `configure' prints some messages telling which + features is it checking for. + + 2. Compile the package by typing: + % make + Running `make' takes a while. If this is a very large package, now + is the time to go make some coffee. + + 3. Some packages are bundled with self-tests for source-code + verification. If this package includes such tests, you can + optionally run them after compilation by typing + % make check + + 4. Type `make install' to install the programs and any data files and + documentation. Type `make uninstall' to undo the installation. + During installation, the following files go to the following directories: + Executables -> /prefix/bin + Libraries -> /prefix/lib + Public header files -> /prefix/include + Man pages -> /prefix/man/man? + Info files -> /prefix/info + where `prefix' is either `/usr/local' or the PATH that you specified + in the `--prefix' flag. + + If any of these directories do not presently exist, they will be + created on demand. + + If you are installing in your home directory make sure that + `/home/luser/bin' is in your path. If you're using the bash shell + add this line at the end of your .cshrc file: + PATH="/home/luser/bin:${PATH}" + export PATH + If you are using csh or tcsh, then use this line instead: + setenv PATH /home/luser/bin:${PATH} + By prepending your home directory to the rest of the PATH you can + override systemwide installed software with your own custom installation. + + 5. You can remove the program binaries and object files from the + source code directory by typing `make clean'. To also remove the + files that `configure' created (so you can compile the package for + a different kind of computer), type `make distclean'. + +Compiler configuration +====================== + + The `configure' shell script is responsible for choosing and configuring +the compiler(s). + +The following options allow you to specify whether you +want to enable or disable various debugging mechanisms: + +`--with-warnings' + Make the compilers very picky about warnings. Try this whenever you + write new code since it may catch a few bugs. This is not active by + default because all too often warnings can be too picky and scare + the end-user. + +`--disable-assert' + Compile without using assertions. This results in faster code, + but should not be used during developerment, or to run `make check' + which depends on assertions. It should only be used for production + runs on code that you believe is bug free. + +All programs are compiled with optimization level 2 by default (-O2). +Occasionally that confuses the debugger when code is inlined. To disable +optimization and enable debugging, set the shell environment variables +CFLAGS, CXXFLAGS, FFLAGS to `-g'. On the bash shell, you can do this +like this: + $ export CFLAGS="-g" + $ export CXXFLAGS="-g" + $ export FFLAGS="-g" +On the tcsh shell, use the `setenv' command instead: + % setenv CFLAGS "-g" + ...etc... +For other shell, please consult your shell's documentation. + +Similarly, you can increase the optimization level by assigning these +variables to "-g -O3". + +The following options allow you to reconsider the `configure' shell script's +choice of Fortran compilers. + +`--with-f2c' + Compile the Fortran code by translating it to C, even if a native + Fortran compiler is available. A copy of the f2c translator should be + bundled in the distribution. It will be compiled and then used to + compile your Fortran code. +`--with-g77' + Compile the Fortran code with g77 even if a proprietary Fortran + compiler is available +`--with-f77=F77' + Compile the Fortran code with the specified Fortran compiler. + +Depending on what languages the package uses, some of these options may +or may not be available. To see what is available, type: + % sh ./configure --help + +About the configure script +========================== + + The `configure' shell script attempts to guess correct values for +various system-dependent variables used during compilation. It uses +those values to create a `Makefile' in each directory of the package. +It may also create one or more `.h' files containing system-dependent +definitions. Finally, it creates a shell script `config.status' that +you can run in the future to recreate the current configuration, a file +`config.cache' that saves the results of its tests to speed up +reconfiguring, and a file `config.log' containing compiler output +(useful mainly for debugging `configure'). + + If you need to do unusual things to compile the package, please try +to figure out how `configure' could check whether to do them, and mail +diffs or instructions to the address given in the `README' so they can +be considered for the next release. If at some point `config.cache' +contains results you don't want to keep, you may remove or edit it. + + The file `configure.in' is used to create `configure' by a program +called `autoconf'. You only need `configure.in' if you want to change +it or regenerate `configure' using a newer version of `autoconf'. + +Advanced installation options. +============================== + + The `configure' script also understands the following more advanced +options, to handle situations for which `--prefix' alone is not sufficient. + + You can specify separate installation prefixes for +architecture-specific files and architecture-independent files. If you +give `configure' the option `--exec-prefix=PATH', the package will use +PATH as the prefix for installing programs and libraries. +Documentation and other data files will still use the regular prefix. + + In addition, if you use an unusual directory layout you can give +options like `--bindir=PATH' to specify different values for particular +kinds of files. Run `configure --help' for a list of the directories +you can set and what kinds of files go in them. + + If the package supports it, you can cause programs to be installed +with an extra prefix or suffix on their names by giving `configure' the +option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. + +Optional Features +================= + + Some packages pay attention to `--enable-FEATURE' options to +`configure', where FEATURE indicates an optional part of the package. +They may also pay attention to `--with-PACKAGE' options, where PACKAGE +is something like `gnu-as' or `x' (for the X Window System). The +`README' should mention any `--enable-' and `--with-' options that the +package recognizes. + + For packages that use the X Window System, `configure' can usually +find the X include and library files automatically, but if it doesn't, +you can use the `configure' options `--x-includes=DIR' and +`--x-libraries=DIR' to specify their locations. diff --git a/Makefile.am b/Makefile.am new file mode 100644 index 0000000..ece163e --- /dev/null +++ b/Makefile.am @@ -0,0 +1,27 @@ +## Process this file with automake to produce Makefile.in + +# Copyright (C) 2000, 2001, 2004, 2006, 2013, 2014 Free Software Foundation, Inc. +# +# This file is free software;

It is now an input char device (cf. TAOCP vol.1 p. 133, + where it is mentioned as the 'paper tape reader'; thanks to Michael + Talbot-Wilson). + +** Listings produced by mixasm improved: better layout, and correct + identification of 'ALF' and 'CON' instructions (including those + added by the compiler as a result of local constant definitions and + future references. + +** Local constants can now be modified by a field spec or an index, + as in, say, CMPA =0=,1(3:2) (closes #5654). + +** The virtual machine reader is now case-insensitive, i.e., it + automatically converts lowercase characters in input char device + files to their uppercase counterparts (which are the only ones + admitted by MIX). The ASCII representation for MIX chars delta, + sigma and pi is now ~, [ and #. + +** Bug fix: mixvm prompt's ending whitespace is now correctly set. + +** Bug fix: blocks in input char devices (e.g. the card reader) are + now expected to be separated by newlines, mirroring char output, + which is done so (i.e. with one ASCII line per block). + +** Improved virtual machine error messages (bad memory address, device + no., fspec, etc.). + +** Bug fix: undefined symbols are transformed to new addresses just + before the end of a compiled program (as per TAOCP v1 p. 156; + thanks to WeiZeng). + +** Bug fix: the vm no longer blows up on memory access violations + (thanks to Joel R. Holveck; closes #5649). + +** Bug fix: LDAN, LDXN and LDiN always negate the result, even if zero + (thanks to Ruslan Batdalov; closes Debian's #247392). + +--------------------------------------------------------------------------- +* Version 1.0.1 (09/06/03) + +** New misc/mixal-mode.el for emacs (and associated docs), written by + Pieter Pareit. + +** Error message for unquoted ALF operand improved. + +** Fixed bug that caused (g)mixvm to segfault when reading a false MIX + file. + +** All translatable strings are ready for i18n. + +** Portability fixes to extend supported platforms. + +** When the program counter reaches address 4000 during program + execution, it is set back to its maximum value, 3999, and the + program halts, to avoid infinite loops. + +** Minor documentation improvements. + +** Minor bug fixes. + +--------------------------------------------------------------------------- +* Version 1.0 (08/04/02) + +** The stable release. + +** New command line option added to 'mixvm': -t (--time) to turn on + virtual execution time printing (it is now off by default). + +** New 'mixvm' command: prompt, lets you change the mixvm command + prompt ("MIX > " by default). + +** When the program counter reaches address 4000 during program + execution, it wraps up to value 0, to keep always a valid + address. Caveat: a program missing the HLT instruction can loop + indefinitely. + +** New supported platform: Mac OS X. + +** User manual reviewed and updated. + +** Bug fix: 'configure' libraries detection now works properly. + +** Bug fix: missing #includes added to avoid compilation errors in + some platforms (RedHat 7.1, ia64 with gcc 3.0). + +--------------------------------------------------------------------------- +* Version 0.5 (29/09/01) + +** Added Guile support: + - New utility 'mixguile': a Guile shell with an embedded MIX + virtual machine. + - gmixvm and mixvm have an embedded Guile interpreter: Scheme + can be used as an extension language. + - See the updated User's Manual for details. + +** New (g)mixvm commands: + - psrc: print the current program's source file path + - pprog: print the current program's path + - pline: print the current program line + - pstat: print the current virtual machine status + - slog: set on/off the logging of info messages to stdout (or + the command log in gmixvm) + +** For the sake of coherence, the following (g)mixvm commands + have been renamed: + - tracing -> strace + - timing -> stime (set on/off timing), + ptime (print timing stats) + - devdir -> sddir (set the devices dir), + pddir (print the devices dir) + +** Major documentation update to include Guile support and various + cosmetic corrections for pretty ps and pdf manuals (provided in the + distribution in addition to the html format). + +** In gmixvm, when a font specified in the config file cannot be + loaded, it is removed from the configuration. + +** gmixvm now accepts the standard command line options -vuh + +** Bug fix: when the MIX font is changed in gmixvm, the loc widget + font is correctly updated. + +** Bug fix: help messages are now correctly aligned in (g)mixvm. + +** Bug fix: timing statitics for the MOVE instruction are correctly + computed. + +** Bug fix: pressing return at an empty 'MIX >' prompt does not + produce an error message. + +** Bug fix: the configure script now correctly detects the absence of + libglade (needed by gmixvm). + +** Bug fix: makefiles corrected so that mdk accepts a VPATH build + ('make distcheck' works now) + +--------------------------------------------------------------------------- +* Version 0.4.2 (17/08/01) + +** New toolbars for gmixvm windows. + +** Toolbars can be hidden, using View->Toolbar checkbox. + +** New icon for the "goto loc pointer address" button. + +** The menu entry "Split windows" has been moved from "Settings" to + "View" main menu, and renamed to "One window" in split mode. + +** In split mode, the MIXAL window has its own statusbar to display + symbol values in it (instead of in the main window toolbar). + +** Bug fix: the visibility of split windows when changing mode is now + correctly handled. + +** Bug fix: the devices window is now correctly destroyed, avoiding + GTK warnings on gmixvm exit. + +--------------------------------------------------------------------------- +* Version 0.4 (22/07/01) + +** Split mode: gmixvm can now be run with the MIXVM, MIXAL and Devices + windows detached (instead of arranged in a notebook). + +** When running in split mode, the MIXVM, MIXAL and Devices windows + can be hidden. + +** Conditional breakpoints can be set in mixvm and gmixvm using the + commands 'sbp[rmco]', which cause the execution to stop when a + given register, memory cell contents, comparison flag or overflow + toggle change (e.g. 'sbpr A' will set a breakpoint on register A + contents change). Conditional breakpoints can be deleted using the + new commands 'cbp[rmco]'. + +** New vm command 'pbt' which prints a backtrace of the last executed + instructions. + +** The gmixvm main window displays the path to the current MIX file in + its title bar. + +** The mixvm and gmixvm configuration files are now stored in ~/.mdk + (instead of ~/.gmixvm). + +** The default device files directory is also ~/.mdk. It can be + configured using the new command 'devdir' or (in gmixvm) with the + new Settings->Devices dir menu command. + +** The commands 'tron' and 'troff' have been substituted by 'tracing + on|off'. + +** The trace flag is saved as a configuration parameter in mixvm and + gmixvm. + +** New vm commands: 'pedit'/'sedit' (print/set editor command) and + 'pasm'/'sasm' (print/set compile command). Their value is stored as + a config param also in mixvm. + +** New command 'timing' for setting on/off and printing the timing + statistics (both in gmixvm and mixvm). Its value is also stored as + a config param. + +** mixvm and gmixvm now save a history file so that they remember + commands typed in previous sessions. + +** Bug fix: changes in the device format are now correctly stored (gmixvm). + +--------------------------------------------------------------------------- +* Version 0.3.5 (23/06/01) + +** In gmixvm, when the mouse pointer is over a MIXAL source line, the + status bar shows the value of the variables appearing in this line. + +** The current symbol table can be displayed, in gmixvm, using the menu + command Debug->Symbols... + +** Bug fix: the load, compile and run file dialogs now get the correct + filename under linux. + +** Bug fix: fonts used by gmixvm are now always correctly saved. + +** Bug fix: 'psym' now works correctly in gmixvm. + +** Bug fix: the symbol table for a MIX file is now correctly recovered + both in gmixvm and mixvm (negative values where incorrectly + converted to a positive value). + +--------------------------------------------------------------------------- +* Version 0.3.4 (12/06/01) + +** Bug fix for a segfault which made gmixvm unusable in version 0.3.3. + +--------------------------------------------------------------------------- +* Version 0.3.3 (10/06/01) + +** The output of the contents of binary devices in gmixvm can be + configured to be in decimal or word format (for each block device). + +** The main gmixvm window is not shown until it is completely drawn. + +** The commands 'edit' and 'compile' are now understood by gmixvm. The + external programs used can be configured using the menu entry + Settings->External programs. + +** The commands 'edit' and 'compile' can be now executed without + argument (both in mixvm and gmixvm).

Also, it might not be +## supported by the other compilers which use the 'gcc' depmode. +## - Using -M directly means running the compiler twice (even worse +## than renaming). + if test -z "$gccflag"; then + gccflag=-MD, + fi + "$@" -Wp,"$gccflag$tmpdepfile" + stat=$? + if test $stat -ne 0; then + rm -f "$tmpdepfile" + exit $stat + fi + rm -f "$depfile" + echo "$object : \\" > "$depfile" + # The second -e expression handles DOS-style file names with drive + # letters. + sed -e 's/^[^:]*: / /' \ + -e 's/^['$alpha']:\/[^:]*: / /' < "$tmpdepfile" >> "$depfile" +## This next piece of magic avoids the "deleted header file" problem. +## The problem is that when a header file which appears in a .P file +## is deleted, the dependency causes make to die (because there is +## typically no way to rebuild the header).

The programmer doesn't actually know whether he is programming a +machine with base 2 or base 10 arithmetic. ... + +Words. The basic unit of information is a -byte-. Each byte contains an +-unspecified- amount of information, but it must be capable of holding at +least 64 distinct values. That is, we know that any number between 0 and +63, inclusive, can be contained in one byte. Furthermore, each byte +contains -at-most- 100 distinct values. On a binary computer a byte must +therefore be composed of six bits; on a decimal computer we have two digits +per byte. + ... An algorithm in MIX should work properly regardless of how big a +byte is. Although it is quite possible to write programs which depend on +the byte size, this is an illegal act which will not be tolerated; the only +legitimate programs are those which would give correct results with all +byte sizes. ... + A computer word is five bytes plus a sign. The sign position has only +two possible values, + and -. + +Registers. There are nine registers in MIX. + + The A-register (Accumulator) is five bytes plus sign. + The X-register (Extension) is also five bytes plus sign. + The I-registers (Index registers) I1, I2, I3, I4, I5, and I6 each hold +two bytes plus sign. + The J-register (Jump address) holds two bytes, and its sign is always +. + +We shall use a small letter ``r'' prefixed to the name, to identify a MIX +register. Thus, ``rA'' means ``register A''. + The A-register has many uses, especially for arithmetic and operating on +data. The X-register is an etension on the ``right-hand side'' of rA, and it +is used in connection with rA to hold ten bytes of a product or dividend, or +it can be used to hold information shifted to the right out of rA. The index +registers rI1, rI2, rI3, rI4, rI5, and rI6 are used primarily for counting and +for referencing variable memory addresses. The J-register always hold the +address of the instruction following the preceding ``JUMP'' intruction, and it +is primarily used in connection with subroutines. + Besides thesee registers, MIX contains + + an overflow toggle (a single bit which is either ``on'' or ``off''), + a comparison indicator (which has three values: less, equal, or greater), + memory (4000 words of storage, each word with five bytes plus sign), + and input-output devices (cards, tapes, etc.). + +Partial fields of words. The five bytes and sign of a computer word are +numbered as follows: + + 0 1 2 3 4 5 + +/- Byte Byte Byte Byte Byte. + +Most of the instructions allow the programmer to use only part of a word if he +chooses. In this case a ``field specification'' is given. The allowable +fields are those which are adjacent in a computer word, and they are +represented by (L:R), where L is the number of the left-hand part and R is the +number of the right-hand part of the field. Examples of field specifications +are: + (0:0), the sign only. + (0:2), the sign and first two bytes. + (0:5), the whole word. This is the most common field specification. + (1:5), the whole word except the sign. + (4:4), the fourth byte only. + (4:5), the two least significant bytes. + +The use of these field specifications varies slightly from instruction to +instruction, and it will be explained in detail for each instruction where +it applies. + Although it is generally not important to the programmer, the field (L:R) +is denoted in the machine by the single number 8L + R, and this number will +fit in one byte. + +Instruction format. Computer words used for instructions have the following +form: + + 0 1 2 3 4 5 (3) + +/- A A I F C. + + The rightmost byte, C, is the operation code telling what operation is to +be performed. For example, C=8 is the operation LDA, ``load the A register''. + The F-byte holds a modification of the operation code. F is usually a +field specification (L:R)=8L + R; for example, if C=8 and F=11, the operation +is ``load the A-register with the (1:3) field''. Sometimes F is used for other +purposes; on input-output instructions, for example, F is the number of the +affected input or output unit. + The left-hand portion of the instruction, +/-AA, is the ``address''. (Note +that the sign is part of the address.) The I-field, which comes next to the +address, is the ``index specification'', which may be used to modify the +address of an instruction. If I=0, the address +/-AA is used without change; +otherwise I should contain a number {i} between 1 and 6, and the contents of +index register I{i} are added algebraically to +/-AA; the result is used as +the address of the instruction. this indexing process takes place on -every- +instruction. We will use the letter M to indicate the address after any +specified indexing has occurred. (If the addition of the index register to the +address +/-AA yields a result which does not fit in two bytes, the value of M +is undefined.) + In most instructions, M will refer to a memory cell. The terms ``memory +cell'' and ``memory location'' are used almost interchangeably in this book. +We assume that there are 4000 memory cells, numbered fro 0 to 3999; hence every +memory location can be addressed with two bytes. For every instruction in +which M is to refer to a memory cell we must have 0 <= M <= 3999, and in this +case we will write CONTENTS(M) to denote the value stored in memory location M. + On certain instructions, the ``address'' M has another significance, and it +may even be negative. Thus, one instruction adds M to an index register, and +this operation takes account of the sign of M. + +Notation. To discuss instructions in a readable manner, we will use the +notation + + OP ADDRESS,I(F) (4) + +to denote an instruction like (3). Here OP is a symbolic name which is given +to the operation code (the C-part) of the instruction; ADDRESS is the +/-AA +portion; and I, F represent the I- and F-fields, respectively. + If I is zero, the ``,I'' is omitted. If F is the -normal- F-specification +for this particular operator, the ``(F)'' need not be written. The normal F- +specification for almost all operators is (0:5), representing a whole word. +If a different F is standard, it will be mentioned explicity when we discuss +a particular operator. + +... + +Rules for each instruction. The remarks following (3) above have defined the +quantities M, F, and C for every word used as an instruction. We will now +define the actions corresponding to each instruction. [Knuth gives C- and F- +values in each instruction's entry; I'm omitting them since you can get them +from the opcodes file in this distribution.] + +Loading operators + +* LDA (load A). +The specified field of CONTENTS(M) replaces the previous contents of register +A. + On all operations where a partial field is used as an input, the sign is +used if it is a part of the field, otherwise the sign + is understood. The +field is shifted over to the right-hand part of the register as it is loaded. + Examples: If F is the normal field specification (0:5), the entire contents +of location M is loaded. If F is (1:5), the absolute value of CONTENTS(M) is +loaded with a plus sign. If M contains an -instruction- word and if F is +(0:2), the ``+/-AA'' field is loaded as + + 0 1 2 3 4 5 + +/- 0 0 0 A A. + +... + +* LDX (load X). +This is the same as LDA, except that rX is loaded instead of rA. + +* LD{i} (load {i}). +This is the same as LDA, except that rI{i} is loaded instead of rA. An index +register contains only two bytes (not five) plus sign; bytes 1, 2, 3 are always +assumed to be zero. The LD{i} instruction is considered undefined if it would +result in setting bytes 1, 2, 3 to anything but zero. + In the description of all instructions, ``{i}'' stands for an integer, +1 <= i <= 6. Thus, LD{i} stands for six different instructions: +LD1, LD2, ..., LD6. + +* LDAN (load A negative). +* LDXN (load X negative). +* LD{i}N (load {i} negative). +These eight instructions are the same as LDA, LDX, LD{i}, respectively, except +that the -opposite- sign is loaded. + +Storing operators. + +* STA (store A). +The contents of rA replaces the field of CONTENTS(M) specified by F. The other +parts of CONTENTS(M) are unchanged. + On a -store- operation the field F has the opposite significance from the +-load- operation. The number of bytes in the field is taken from the right- +hand side of the the register and shifted -left- if necessary to be inserted in +the proper field of CONTENTS(M). The sign is not altered unless it is part of +the field. The contents of the register is not affected. + +... + +* STX (store X). +Same as STA except rX is stored rather than rA. + +* ST{i} (store {i}). +Same as STA except rI{i} is stored rather than rA. Bytes 1, 2, 3 of an index +register are zero; thus if rI1 contains + + +/- m n + +this behaves as though it were + + 0 1 2 3 4 5 + +/- 0 0 0 m n. + +* STJ (store J). +Same as ST{i} except rJ is stored, and its sign is always +. + On STJ the normal field specification for F is (0:2), -not- (0:5). This is +natural, since STJ is almost always done into the address field of an +instruction. + +* STZ (store zero). +Same as STA except plus zero is stored. In other words, the specified field of +CONTENTS(M) is cleared to zero. + +Arithmetic operators. On the add, subtract, multiply, and divide operations a +field specification is allowed. A field specification of ``(0:6)'' can be used +to indicate a ``floating-point'' operation (see Section 4.2 [in Volume 2]), but +few of the programs we will write for MIX will use this feature... + The standard field specification is, as usual, (0:5). Other fields are +treated as in LDA. We will use the letter V to indicate the specified field of +CONTENTS(M); thus, V is the value which would have been loaded into register A +if the operation code were LDA. + +* ADD. +V is added to rA. If the magnitude of the result is too large for register A, +the overflow toggle is set on, and the remainder of the addition appearing in +rA is as though a ``1'' had been carried into another register to the left of +A. (Otherwise the setting of the overflow toggle is unchanged.) If the result +is zero, the sign of rA is unchanged. + + Example: The sequence of instructions below gives the sum of the five +bytes of register A. + + STA 2000 + LDA 2000(5:5) + ADD 2000(4:4) + ADD 2000(3:3) + ADD 2000(2:2) + ADD 2000(1:1) + +This is sometimes called ``sideways addition''. + +* SUB (subtract). +V is subtracted from rA. Overflow may occur as in ADD. + Note that because of the variable definition of byte size, overflow will +occur in some MIX computers when it would not occur in others... + +* MUL (multiply). +The 10-byte product of V times (rA) replaces registers A and X. The signs of +rA and rX are both set to the algebraic sign of the result (i.e., + if the +signs of V and rA were the same, and - if they were different). + +* DIV (divide). +The value of rA and rX, treated as a 10-byte number, with the sign of rA, is +divided by the value V. If V=0 or if the quotient is more than five bytes in +magnitude (this is equivalent to the condition that |rA| >= |V|), registers A +and X are filled with undefined information and the overflow toggle is set on. +Otherwise the quotient is placed in rA and the remainder is placed in rX. The +sign of rA afterward is the algebraic sign of the quotient; the sign of rX +afterward is the previous sign of rA. + +... + +Address transfer operators. In the following operations, the (possibly +indexed) ``address'' M is used as a signed number, not as the address of a +cell in memory. + +* ENTA (enter A). +The quantity M is loaded into rA. The action is equivalent to ``LDA'' from a +memory word containing the signed value of M. If M=0, the sign of the +instruction is loaded. [I don't think the simulator works that way. Better +check...] + + Examples: ``ENTA 0'' sets rA to zeros. ``ENTA 0,1'' sets rA to the current +contents of index register 1, except that -0 is changed to +0. + +* ENTX (enter X). +* ENT{i} (enter {i}). +Analogous to ENTA, loading the appropriate register. + +* ENNA (enter negative A). +* ENNX (enter negative X). +* ENN{i} (enter negative {i}). +Same as ENTA, ENTX, and ENT{i}, except that the opposite sign is loaded. + + Example: ``ENN3 0,3'' replaces rI3 by its negative. + +* INCA (increase A). +The quantity M is added to rA; the action is equivalent to ``ADD'' from a +memory word containing the value of M. Overflow is possible and it is treated +just as in ADD. + + Example: ``INCA 1'' increases the value of rA by one. + +* INCX (increase X). +The quantity M is added to rX. If overflow occurs, the action is equivalent to +ADD, except that rX is used instead of rA. Register A is never affected by +this instruction. + +* INC{i} (increase {i}). +Add M to rI{i}. Overflow must not occur; if the magnitude of the result is +more than two bytes, the result of this instruction is undefined. + +* DECA (decrease A). +* DECX (decrease X). +* DEC{i} (decrease {i}). +These eight instructions are the same as INCA, INCX, and INC{i}, respectively, +except that M is subtracted from the register rather than added. + Note that the operation code C is the same for ENTA, ENNA, INCA, AND DECA; +the F-field is used to distinguish the various operations in this case. + +Comparison operators. The comparison operators all compare the value contained +in a register with a value contained in memory. The comparison indicator is +then set to LESS, EQUAL, or GREATER according to whether the value of the +-register- is less than, equal to, or greater than the value of the -memory- +-cell-. A minus zero is -equal-to- a plus zero. + +* CMPA (compare A). +The specified field of A is compared with the -same- field of CONTENTS(M). If +the field F does not include the sign position, the fields are both thought of +as positive; otherwise the sign is taken into account in the comparison. (If +F is (0:0) an equal comparison always occurs, since minus zero equals plus +zero.) + +* CMPX (compare X). +This is analogous to CMPA. + +* CMP{i} (compare {i}). +Analogous to CMPA. Bytes 1, 2, and 3 of the index register are treated as +zero in the comparison. (Thus if F = (1:2), the result cannot be GREATER.) + +Jump operators. Ordinarily, instructions are executed in sequential oder; +i.e., the instruction executed after the one in location P is the instruction +found in location P+1. Several ``jump'' instructions allow this sequence to +be interrupted. When such a jump takes place, the J-register is normally set +to the address of the next instruction (that is, the address of the instruction +which would have been next if we hadn't jumped). A ``store J'' instruction +then can be used by the programmer, if desired, to set the address field of +another command which will later be used to return to the original place in the +program. The J-register is changed whenever a jump actually occurs in a +program (except JSJ), and it is never changed except when a jump occurs. + + +* JMP (jump). +Unconditional jump: the next instruction is taken from location M. + +* JSJ (jump, save J). +Same as JMP except that the contents of rJ are unchanged. + +* JOV (jump on overflow). +If the overflow toggle is on, it is turned off and a JMP occurs; otherwise +nothing happens. + +* JNOV (jump on no overflow). +If the overflow toggle is off, a JMP occurs; otherwise it is turned off. + +* JL, JE, JG, JGE, JNE, JLE (jump on less, equal, greater, greater-or-equal, +unequal, less-or-equal). +Jump if the comparison indicator is set to the condition indicated. For +example, JNE will jump if the comparison indicator is LESS or GREATER. The +comparison indicator is not changed by these instructions. + +* JAN, JAZ, JAP, JANN, JANZ, JANP (jump A negative, zero, positive, +nonnegative, nonzero, nonpositive). +If the contents of rA satisfy the stated condition, a JMP occurs, otherwise +nothing happens. ``Positive'' means -greater- than zero (not zero); +``nonpositive'' means the opposite, i.e., zero or negative. + +* JXN, JXZ, JXP, JXNN, JXNZ, JXNP (jump X negative, zero, positive, +nonnegative, nonzero, nonpositive). +* J{i}N, J{i}Z, J{i}P, J{i}NN, J{i}NZ, J{i}NP (jump {i} negative, zero, positive, +nonnegative, nonzero, nonpositive). +These are analogous to the corresponding operations for rA. + +Miscellaneous operators. + +* MOVE. +The number of words specified by F is moved, starting from location M to the +location specified by the contents of index register 1. The transfer occurs +one word at a time, and rI1 is increased by the value of F at the end of the +operation. If F=0, nothing happens. + Care must be taken when the groups of locations involved overlap... + +* SLA, SRA, SLAX, SRAX, SLC, SRC (shift left A, shift right A, shift left AX, +shift right AX, shift left AX circularly, shift right AX circularly). + These are the ``shift'' commands. Signs of registers A, X are not affected +in any way. M specifies the number of -bytes- to be shifted left or right; M +must be nonnegative. SLA and SRA do not affect rX; the other shifts affect +both registers as though they were a single 10-byte register. With SLA, SRA, +SLAX, and SRAX, zeros are shifted into the register at one side, and bytes +disappear at the other side. The instructions SLC and SRC call for a +``circulating'' shift, in which the bytes that leave one end enter in at the +other end. Both rA and rX participate in a circulating shift. + + Examples: + Register A Register X + Initial contents + 1 2 3 4 5 - 6 7 8 9 10 + SRAX 1 + 0 1 2 3 4 - 5 6 7 8 9 + SLA 2 + 2 3 4 0 0 - 5 6 7 8 9 + SRC 4 + 6 7 8 9 2 - 3 4 0 0 5 + SRA 2 + 0 0 6 7 8 - 3 4 0 0 5 + SLC 501 + 0 6 7 8 3 - 4 0 0 5 0 + +* NOP (no operation). +No operation occurs, and this instruction is bypassed. F and M are ignored. + +* HLT (halt). +The machine stops. When the computer operator restarts it, the net effect is +equivalent to NOP. + +Input-output operators. MIX has a fair amount of input-output equipment (all +of which is optional at extra cost). Each device is given a number as follows: + + Unit number Peripheral device Block size + t Tape unit no. t (0 <= t <= 7) 100 words + d Disk or drum unit no. d (8 <= d <= 15) 100 words + 16 Card reader 16 words + 17 Card punch 16 words + 18 Printer 24 words + 19 Typewriter and paper tape 14 words + +Not every MIX installation will have all of this equipment available; we will +occasionally make appropriate assumptions about the presence of certain +devices. Some devices may not be used both for input and for output. The +number of words mentioned in the above tble is a fixed block size associated +with each unit. + Input or output with magnetic tape, disk, or drum units reads or writes +full words (five bytes plus sign). Input or output with units 16 through 19, +however, is always done in a -character-code- where each byte represents one +alphnumeric character. Thus, five characters per MIX word are transmitted. +The character code is given [in charset.c]... It is not possible to read in +or write out all possible values a byte may have, since certain combinations +are undefined. Not all input-output devices are capable of handling all the +symbols in the character set; for example, the symbols phi and pi which appear +amid the letters will perhaps not be acceptable to the card reader. When input +of character code is being done, the signs of all words are set to ``+''; on +output, signs are ignored. + The disk and drum units are large external memory devices each containing +b^2 100-word blocks, where b is the byte size. On every IN, OUT, or IOC +instruction as defined below, the particular 100-word block referred to by the +instruction is specified by the current contents of the two least significant +bytes of rX. + +* IN (input). C=36; F=unit. +This instruction initiates the transfer of information from the input unit +specified into consecutive locations starting with M. The number of locations +transferred is the block size for this unit (see the table above). The machine +will wait at this point if a preceding operation for the same unit is not yet +complete. The transfer of information which starts with this instruction will +not be complete until somewhat later, depending on the speed of the input +device, so a program must not refer to the information in memory until then. +It is improper to attempt to read any record from magnetic tape which follows +the latest record written on that tape. + +* OUT (output). C=37; F=unit. +This instruction starts the transfer of information from memory locations +starting at M to the output unit specified. (The machine waits until the unit +is ready, if it is not initially ready.) The transfer will not be complete +until somewhat later, depending on the speed of the output device, so a program +must not alter the information in memory until then. + +* IOC (input-output control). C=35; F=unit. +The machine waits, if necessary, until the specified unit is not busy. Then a +control operation is performed, depending on the particular device being used. +The following examples are used in various parts of this book: + Magnetic tape: If M=0, the tape is rewound. If M<0 the tape is skipped +backward -M records, or to the beginning of the tape, whichever comes first. +If M>0, the tape is skipped forward; it is improper to skip forward over any +records following the one last written on that tape. + For example, the sequence ``OUT 100(3); IOC -1(3); IN 2000(3)'' writes out +one hundred words onto tape 3, then reads it back in again. Unless the tape +reliability is questioned, the last two instructions of that sequence are only +a slow way to move words 1000-1099 to locations 2000-2099. The sequence +``OUT 1000(3); IOC +1(3)'' is improper. + Disk or drum: M should be zero. The effect is to position the device +according to rX so that the next IN or OUT operation on this unit will take +less time if it uses the same rX setting. + Printer: M should be zero. ``IOC 0(18)'' skips the printer to the top of +the following page. + Paper tape reader: Rewind the tape. (M should be zero). + +* JRED (jump ready). C=38; F=unit. +A jump occurs if the specified unit is ready, i.e., finished with the preceding +operation initiated by IN, OUT, or IOC. + +* JBUS (jump busy). C=34; F=unit. +Same as JRED except the jump occurs under the opposite circumstances, i.e., +when the specified unit is -not- ready. + Example: In location 1000, the instruction ``JBUS 1000(16)'' will be +executed repeatedly until unit 16 is ready. + + The simple operations above complete MIX's repertoire of input-output +instructions. There is no ``tape check'' indicator, etc... + +Conversion Operators. + +* NUM (convert to numeric). +This operation is used to change the character code into numeric code. M is +ignored. Registers A, X are assumed to contain a 10-byte number in character +code; the NUM instruction sets the magnitude of rA equal to the numerical value +of this number (treated as a decimal number). The value of rX and the sign of +rA are unchanged. Bytes 00, 10, 20, 30, 40, ... convert to the digit zero; +bytes 01, 11, 21, ... convert to the digit one; etc. Overflow is possible, and +in this case the remainder modulo the word size is retained. + +* CHAR (convert to characters). +This operation is used to change numeric code into character code suitable for +output to cards or printer. The value in rA is converted into a 10-byte +decimal number which is put into register A and X in character code. The signs +of rA, rX are unchanged. M is ignored. + +... + +Timing. To give quantitative information as to how ``good'' MIX programs are, +each of MIX's operations is assigned an execution time typical for present-day +computers. + ADD, SUB, all LOAD operations, all STORE operations (including STZ), all +shift commands, and all comparison operations take two units of time. MOVE +requires one unit plus two for each word moved. MUL requires 10 and DIV +requires 12 units. Execution time for floating-point operations is +unspecified. All remaining operations take one unit of time, plus the time +the computer may be idle on the IN, OUT, IOC, or HLT instructions. + Note in particular that ENTA takes on unit of time, while LDA takes two +units. The timing rules are easily remembered because of the fact that, except +for shifts, MUL, and DIV, the number of units equals the number of references +to memory (including the reference to the instruction itself). + The ``unit'' of time is a relative measure which we will denote simply by +u. It may be regarded as, say, 10 microseconds (for a relatively inexpensive +computer) or as 1 microsecond (for a relatively high-priced machine). + Example: the sequence LDA 1000; INCA 1; STA 1000 takes exactly 5u. diff --git a/doc/Makefile.am b/doc/Makefile.am new file mode 100644 index 0000000..e127057 --- /dev/null +++ b/doc/Makefile.am @@ -0,0 +1,27 @@ +## Process this file with automake to produce Makefile.in + +# Copyright (C) 2000, 2001, 2003, 2004, 2006, 2008, 2013 Free Software +# Foundation, Inc. +# +# This file is free software;

Knuth uses an imaginary computer, the MIX, and its +associated machine-code and assembly languages to illustrate the +concepts and algorithms as they are presented. + + The MIX's architecture is a simplified version of those found in real +CISC CPUs, and the MIX assembly language (MIXAL) provides a set of +primitives that will be very familiar to any person with a minimum +experience in assembly programming. The MIX/MIXAL definition is +powerful and complete enough to provide a virtual development platform +for writing quite complex programs, and close enough to real computers +to be worth using when learning programming techniques. At any rate, if +you want to learn or improve your programming skills, a MIX development +environment would come in handy. + + The MDK package aims at providing such virtual development +environment on a GNU box. Thus, MDK offers you a set of utilities to +simulate the MIX computer and to write, compile, run and debug MIXAL +programs. As of version 1.2.9, MDK includes the following programs: + +'mixasm' + MIXAL assembler. Assembler which translates MIXAL source files + into programs that can be run (and debugged) by 'mixvm', 'mixguile' + or 'gmixvm'. +'mixvm' + MIX virtual machine. Emulation of the MIX computer with a CLI. +'gmixvm' + A GTK+ GUI for the MIX virtual machine. Provides all of 'mixvm' + functionality accessible through a graphical interface. +'mixguile' + A Guile shell, with an embedded MIX virtual machine and built-in + commands to manipulate it using Scheme. +'mixal-mode.el' + An Emacs major mode for MIXAL source files editing, providing + syntax highlighting, documentation lookup and invocation of 'mixvm' + within Emacs. +'mixvm.el' + This elisp program allows running 'mixvm' inside an Emacs GUD + buffer, providing concurrent edition and debugging of MIXAL + programs. + + 'mixvm' and 'gmixvm' implement a simulator of the MIX computer, +giving you a virtual machine for executing and debugging MIX programs. +These binary programs could be written by hand, but it is easier to +produce them compiling MIXAL source files, using the MIXAL assembler +'mixasm'. On the other hand, 'mixguile' offers you the possibility of +manipulating a MIX virtual machine through a set of Scheme functions, so +that you can use this programming language to interact with the virtual +machine. In addition, 'mixvm' and 'gmixvm' are also able to interpret +Scheme scripts (using an embedded Guile interpreter), that is, you can +use Scheme as an extension language to add new functionalities to these +programs. + + This manual gives you a tutorial of MIX and MIXAL, and a thorough +description of the use of the MDK utilities. + + +File: mdk.info, Node: Acknowledgments, Next: Installing MDK, Prev: Introduction, Up: Top + +Acknowledgements +**************** + +Many people have further contributed to MDK by reporting problems, +suggesting various improvements, or submitting actual code.

Graphically, + + ----------------------------------------------- + | 0 | 1 | 2 | 3 | 4 | 5 | + ----------------------------------------------- + | +/- | byte | byte | byte | byte | byte | + ----------------------------------------------- +Sample MIX words are '- 12 00 11 01 63' and '+ 12 11 34 43 00'. + + You can refer to subfields within a word using a "field +specification" or "fspec" of the form "(L:R)", where L denotes the first +byte, and R the last byte of the subfield. When L is zero, the subfield +includes the word's sign. An fspec can also be represented as a single +value 'F', given by 'F = 8*L + R' (thus the fspec '(1:3)', denoting the +first three bytes of a word, is represented by the integer 11). + + The MIX computer stores information in "registers", that can store +either a word or two bytes and sign (see below), and "memory cells", +each one containing a word. Specifically, the MIX computer has 4000 +memory cells with addresses 0 to 3999 (i.e., two bytes are enough to +address a memory cell) and the following registers: + +'rA' + A register. General purpose register holding a word. Usually its + contents serves as the operand of arithmetic and storing + instructions. +'rX' + X register. General purpose register holding a word. Often it + acts as an extension or a replacement of 'rA'. +'rJ' + J (jump) register. This register stores positive two-byte values, + usually representing a jump address. +'rI1', 'rI2', 'rI3', 'rI4', 'rI5', 'rI6' + Index registers. These six registers can store a signed two-byte + value. Their contents are used as indexing values for the + computation of effective memory addresses. + +In addition, the MIX computer contains: + + - An "overflow toggle" (a single bit with values "on" or "off"). In + this manual, this toggle is denoted OV. + - A "comparison indicator" (having three values: "EQUAL", "GREATER" + or "LESS"). In this manual, this indicator is denoted CM, and its + possible values are abbreviated as "E", "G" and "L". + - Input-output block devices. Each device is labelled as 'un', where + 'n' runs from 0 to 20. In Knuth's definition, 'u0' through 'u7' + are magnetic tape units, 'u8' through '15' are disks and drums, + 'u16' is a card reader, 'u17' is a card writer, 'u18' is a line + printer and, 'u19' is a typewriter terminal, and 'u20', a paper + tape. Our implementation maps these devices to disk files, except + for 'u19', which represents the standard output. + + As noted above, the MIX computer communicates with the external world +by a set of input-output devices which can be "connected" to it. The +computer interchanges information using blocks of words whose length +depends on the device at hand (*note Devices::). These words are +interpreted by the device either as binary information (for devices +0-16), or as representing printable characters (devices 17-20). In the +last case, each MIX byte is mapped onto a character according to the +following table: + +00 01 A 02 B 03 C +04 D 05 E 06 F 07 G +08 H 09 I 10 ~ 11 J +12 K 13 L 14 M 15 N +16 O 17 P 18 Q 19 R +20 [ 21 # 22 S 23 T +24 U 25 V 26 W 27 X +28 Y 29 Z 30 0 31 1 +32 2 33 3 34 4 35 5 +36 6 37 7 38 8 39 9 +40 . 41 , 42 ( 43 ) +44 + 45 - 46 * 47 / +48 = 49 $ 50 < 51 > +52 @ 53 ; 54 : 55 ' +The value 0 represents a whitespace. The characters '~', '[' and '#' +correspond to symbols not representable as ASCII characters (uppercase +delta, sigma and gamma, respectively), and byte values 56-63 have no +associated character. + + Finally, the MIX computer features a virtual CPU which controls the +above components, and which is able to execute a rich set of +instructions (constituting its machine language, similar to those +commonly found in real CPUs), including arithmetic, logical, storing, +comparison and jump instructions. Being a typical von Neumann computer, +the MIX CPU fetches binary instructions from memory sequentially (unless +a jump instruction is found), and stores the address of the next +instruction to be executed in an internal register called "location +counter" (also known as program counter in other architectures). + + The next section, *Note MIX instruction set::, gives a complete +description of the available MIX binary instructions. + + +File: mdk.info, Node: MIX instruction set, Prev: MIX architecture, Up: The MIX computer + +2.1.2 MIX instruction set +------------------------- + +The following subsections fully describe the instruction set of the MIX +computer.

Combined with the INDEX + field, denotes the memory address to be used + by the instruction. +INDEX (3:3) The third byte is the "index", normally used + for indexing the address(1) + (*note Instruction structure-Footnote-1::). +MOD (4:4) Byte four is used either as an operation code + modifier or as a field specification. +OPCODE (5:5) The last (least significant) byte in the word + denotes the operation code. + +or, graphically, + + ------------------------------------------------ + | 0 | 1 | 2 | 3 | 4 | 5 | + ------------------------------------------------ + | ADDRESS | INDEX | MOD | OPCODE | + ------------------------------------------------ + + For a given instruction, 'M' stands for the memory address obtained +after indexing the ADDRESS subfield (using its INDEX byte), and 'V' is +the contents of the subfield indicated by MOD of the memory cell with +address 'M'. For instance, suppose that we have the following contents +of MIX registers and memory cells: + + [rI2] = + 00 63 + [31] = - 10 11 00 11 22 +where '[n]' denotes the contents of the nth memory cell and '[rI2]' the +contents of register 'rI2'(2) (*note Instruction +structure-Footnote-2::). Let us consider the binary instruction +'I = - 00 32 02 11 10'. For this instruction we have: + + ADDRESS = - 00 32 = -32 + INDEX = 02 = 2 + MOD = 11 = (1:3) + OPCODE = 10 + + M = ADDRESS + [rI2] = -32 + 63 = 31 + V = [M](MOD) = (- 10 11 00 11 22)(1:3) = + 00 00 10 11 00 + + Note that, when computing 'V' using a word and an fspec, we apply a +left padding to the bytes selected by 'MOD' to obtain a complete word as +the result. + + In the following subsections, we will assign to each MIX instruction +a mnemonic, or symbolic name. For instance, the mnemonic of 'OPCODE' 10 +is 'LD2'. Thus we can rewrite the above instruction as + + LD2 -32,2(1:3) +or, for a generic instruction: + + MNEMONIC ADDRESS,INDEX(MOD) +Some instructions are identified by both the OPCODE and the MOD fields. +In these cases, the MOD will not appear in the above symbolic +representation. Also when ADDRESS or INDEX are zero, they can be +omitted. Finally, MOD defaults to (0:5) (meaning the whole word). + + +File: mdk.info, Node: Instruction structure-Footnotes, Up: Instruction structure + + (1) The actual memory address the instruction refers to, is obtained +by adding to ADDRESS the value of the 'rI' register denoted by INDEX. + + (2) In general, '[X]' will denote the contents of entity 'X'; thus, +by definition, 'V = [M](MOD)'. + + +File: mdk.info, Node: Loading operators, Next: Storing operators, Prev: Instruction structure, Up: MIX instruction set + +2.1.2.2 Loading operators +......................... + +The following instructions are used to load memory contents into a +register. + +'LDA' + Put in rA the contents of cell no. M. OPCODE = 8, MOD = fspec. + 'rA <- V'. +'LDX' + Put in rX the contents of cell no. M. OPCODE = 15, MOD = fspec. + 'rX <- V'. +'LDi' + Put in rIi the contents of cell no. M. OPCODE = 8 + i, MOD = + fspec. 'rIi <- V'. +'LDAN' + Put in rA the contents of cell no. M, with opposite sign. OPCODE + = 16, MOD = fspec. 'rA <- -V'. +'LDXN' + Put in rX the contents of cell no. M, with opposite sign. OPCODE + = 23, MOD = fspec. 'rX <- -V'. +'LDiN' + Put in rIi the contents of cell no. M, with opposite sign. OPCODE + = 16 + i, MOD = fspec. 'rIi <- -V'. + + In all the above load instructions the 'MOD' field selects the bytes +of the memory cell with address 'M' which are loaded into the requisite +register (indicated by the 'OPCODE'). For instance, the word +'+ 00 13 01 27 11' represents the instruction + + LD3 13,1(3:3) + ^ ^ ^ ^ + | | | | + | | | --- MOD = 27 = 3*8 + 3 + | | --- INDEX = 1 + | --- ADDRESS = 00 13 + --- OPCODE = 11 + Let us suppose that, prior to this instruction execution, the state +of the MIX computer is the following: + + [rI1] = - 00 01 + [rI3] = + 24 12 + [12] = - 01 02 03 04 05 +As, in this case, 'M = 13 + [rI1] = 12', we have + + V = [M](3:3) = (- 01 02 03 04 05)(3:3) + = + 00 00 00 00 03 +(note that the specified subfield is left-padded with null bytes to +complete a word). Hence, the MIX state, after the instruction +execution, will be + + [rI1] = - 00 01 + [rI3] = + 00 03 + [12] = - 01 02 03 04 05 + + To further illustrate loading operators, the following table shows +the contents of 'rX' after different 'LDX' instructions: + +'LDX 12(0:0) [rX] = - 00 00 00 00 00' +'LDX 12(0:1) [rX] = - 00 00 00 00 01' +'LDX 12(3:5) [rX] = + 00 00 03 04 05' +'LDX 12(3:4) [rX] = + 00 00 00 03 04' +'LDX 12(0:5) [rX] = - 01 02 03 04 05' + + +File: mdk.info, Node: Storing operators, Next: Arithmetic operators, Prev: Loading operators, Up: MIX instruction set + +2.1.2.3 Storing operators +......................... + +The following instructions are the inverse of the load operations: they +are used to store a subfield of a register into a memory location. +Here, MOD represents the subfield of the memory cell that is to be +overwritten with bytes from a register. These bytes are taken beginning +by the rightmost side of the register. + +'STA' + Store rA. OPCODE = 24, MOD = fspec. 'V <- rA'. +'STX' + Store rX. OPCODE = 31, MOD = fspec. 'V <- rX'. +'STi' + Store rIi. OPCODE = 24 + i, MOD = fspec. 'V <- rIi'. +'STJ' + Store rJ. OPCODE = 32, MOD = fspec. 'V <- rJ'. +'STZ' + Store zero. OPCODE = 33, MOD = fspec. 'V <- 0'. + + By way of example, consider the instruction 'STA 1200(2:3)'. It +causes the MIX to fetch bytes no. 4 and 5 of register A and copy them +to bytes 2 and 3 of memory cell no. 1200 (remember that, for these +instructions, MOD specifies a subfield of _the memory address_). The +other bytes of the memory cell retain their values. Thus, if prior to +the instruction execution we have + + [1200] = - 20 21 22 23 24 + [rA] = + 01 02 03 04 05 +we will end up with + + [1200] = - 20 04 05 23 24 + [rA] = + 01 02 03 04 05 + + As a second example, 'ST2 1000(0)' will set the sign of '[1000]' to +that of '[rI2]'. + + +File: mdk.info, Node: Arithmetic operators, Next: Address transfer operators, Prev: Storing operators, Up: MIX instruction set + +2.1.2.4 Arithmetic operators +............................ + +The following instructions perform arithmetic operations between rA and +rX register and memory contents. + +'ADD' + Add and set OV if overflow. OPCODE = 1, MOD = fspec. + 'rA <- rA +V'. +'SUB' + Sub and set OV if overflow. OPCODE = 2, MOD = fspec. + 'rA <- rA - V'. +'MUL' + Multiply V times rA and store the 10-bytes product in rAX. OPCODE = + 3, MOD = fspec. 'rAX <- rA x V'. +'DIV' + rAX is considered a 10-bytes number, and it is divided by V. OPCODE + = 4, MOD = fspec. 'rA <- rAX / V', 'rX' <- reminder. + + In all the above instructions, '[rA]' is one of the operands of the +binary arithmetic operation, the other being 'V' (that is, the specified +subfield of the memory cell with address 'M'), padded with zero bytes on +its left-side to complete a word. In multiplication and division, the +register 'X' comes into play as a right-extension of the register 'A', +so that we are able to handle 10-byte numbers whose more significant +bytes are those of 'rA' (the sign of this 10-byte number is that of +'rA': 'rX''s sign is ignored). + + Addition and subtraction of MIX words can give rise to overflows, +since the result is stored in a register with room to only 5 bytes (plus +sign). When this occurs, the operation result modulo 1,073,741,823 (the +maximum value storable in a MIX word) is stored in 'rA', and the +overflow toggle is set to TRUE. + + +File: mdk.info, Node: Address transfer operators, Next: Comparison operators, Prev: Arithmetic operators, Up: MIX instruction set + +2.1.2.5 Address transfer operators +.................................. + +In these instructions, 'M' (the address of the instruction after +indexing) is used as a number instead of as the address of a memory +cell. Consequently, 'M' can have any valid word value (i.e., it's not +limited to the 0-3999 range of a memory address). + +'ENTA' + Enter 'M' in [rA]. OPCODE = 48, MOD = 2. 'rA <- M'. +'ENTX' + Enter 'M' in [rX]. OPCODE = 55, MOD = 2. 'rX <- M'. +'ENTi' + Enter 'M' in [rIi]. OPCODE = 48 + i, MOD = 2. 'rIi <- M'. +'ENNA' + Enter '-M' in [rA]. OPCODE = 48, MOD = 3.

'rA <- rA + M'. +'INCX' + Increase [rX] by 'M'. OPCODE = 55, MOD = 0. 'rX <- rX + M'. +'INCi' + Increase [rIi] by 'M'. OPCODE = 48 + i, MOD = 0. 'rIi <- rIi + + M'. +'DECA' + Decrease [rA] by 'M'. OPCODE = 48, MOD = 1. 'rA <- rA - M'. +'DECX' + Decrease [rX] by 'M'. OPCODE = 55, MOD = 1. 'rX <- rX - M'. +'DECi' + Decrease [rIi] by 'M'. OPCODE = 48 + i, MaOD = 0. 'rIi <- rIi - + M'. + + In the above instructions, the subfield 'ADDRESS' acts as an +immediate (indexed) operand, and allow us to set directly the contents +of the MIX registers without an indirection to the memory cells (in a +real CPU this would mean that they are faster that the previously +discussed instructions, whose operands are fetched from memory). So, if +you want to store in 'rA' the value -2000 (- 00 00 00 31 16), you can +use the binary instruction + 31 16 00 03 48, or, symbolically, + + ENNA 2000 +Used in conjunction with the store operations ('STA', 'STX', etc.), +these instructions also allow you to set memory cells contents to +concrete values. + + Note that in these address transfer operators, the 'MOD' field is not +a subfield specificator, but serves to define (together with 'OPCODE') +the concrete operation to be performed. + + +File: mdk.info, Node: Comparison operators, Next: Jump operators, Prev: Address transfer operators, Up: MIX instruction set + +2.1.2.6 Comparison operators +............................ + +So far, we have learned how to move values around between the MIX +registers and its memory cells, and also how to perform arithmetic +operations using these values. But, in order to write non-trivial +programs, other functionalities are needed. One of the most common is +the ability to compare two values, which, combined with jumps, will +allow the execution of conditional statements. The following +instructions compare the value of a register with 'V', and set the CM +indicator to the result of the comparison (i.e. to 'E', 'G' or 'L', +equal, greater or lesser respectively). + +'CMPA' + Compare [rA] with V. OPCODE = 56, MOD = fspec. +'CMPX' + Compare [rX] with V. OPCODE = 63, MOD = fspec. +'CMPi' + Compare [rIi] with V. OPCODE = 56 + i, MOD = fspec. + + As explained above, these instructions modify the value of the MIX +comparison indicator; but maybe you are asking yourself how do you use +this value: enter jump operators, in the next subsection. + + +File: mdk.info, Node: Jump operators, Next: Input-output operators, Prev: Comparison operators, Up: MIX instruction set + +2.1.2.7 Jump operators +...................... + +The MIX computer has an internal register, called the "location +counter", which stores the address of the next instruction to be fetched +and executed by the virtual CPU. You cannot directly modify the contents +of this internal register with a load instruction: after fetching the +current instruction from memory, it is automatically increased in one +unit by the MIX. However, there is a set of instructions (which we call +jump instructions) which can alter the contents of the location counter +provided some condition is met. When this occurs, the value of the next +instruction address that would have been fetched in the absence of the +jump is stored in 'rJ' (except for 'JSJ'), and the location counter is +set to the value of 'M' (so that the next instruction is fetched from +this new address). Later on, you can return to the point when the jump +occurred reading the address stored in 'rJ'. + + The MIX computer provides the following jump instructions: With these +instructions you force a jump to the specified address. Use 'JSJ' if +you do not care about the return address. + +'JMP' + Unconditional jump. OPCODE = 39, MOD = 0. +'JSJ' + Unconditional jump, but rJ is not modified. OPCODE = 39, MOD = 1. + + These instructions check the overflow toggle to decide whether to +jump or not. + +'JOV' + Jump if OV is set (and turn it off). OPCODE = 39, MOD = 2. +'JNOV' + Jump if OV is not set (and turn it off). OPCODE = 39, MOD = 3. + + In the following instructions, the jump is conditioned to the +contents of the comparison flag: + +'JL' + Jump if '[CM] = L'. OPCODE = 39, MOD = 4. +'JE' + Jump if '[CM] = E'. OPCODE = 39, MOD = 5. +'JG' + Jump if '[CM] = G'. OPCODE = 39, MOD = 6. +'JGE' + Jump if '[CM]' does not equal 'L'.

OPCODE = 39, MOD = 9. + + You can also jump conditioned to the value stored in the MIX +registers, using the following instructions: + +'JAN' +'JAZ' +'JAP' +'JANN' +'JANZ' +'JANP' +'JAE' +'JAO' + Jump if the content of rA is, respectively, negative, zero, + positive, non-negative, non-zero, non-positive, even or odd. + OPCODE = 40, MOD = 0, 1, 2, 3, 4, 5, 6, 7. +'JXN' +'JXZ' +'JXP' +'JXNN' +'JXNZ' +'JXNP' +'JXE' +'JXO' + Jump if the content of rX is, respectively, negative, zero, + positive, non-negative, non-zero, non-positive, even or odd. + OPCODE = 47, MOD = 0, 1, 2, 3, 4, 5, 6, 7. +'JiN' +'JiZ' +'JiP' +'JiNN' +'JiNZ' +'JiNP' + Jump if the content of rIi is, respectively, negative, zero, + positive, non-negative, non-zero or non-positive.

To that end, you +have at your disposal the following instructions: + +'IN' + Transfer a block of words from the specified unit to memory, + starting at address M. OPCODE = 36, MOD = I/O unit. +'OUT' + Transfer a block of words from memory (starting at address M) to + the specified unit. OPCODE = 37, MOD = I/O unit. +'IOC' + Perform a control operation (given by M) on the specified unit. + OPCODE = 35, MOD = I/O unit. +'JRED' + Jump to M if the specified unit is ready. OPCODE = 38, MOD = I/O + unit. +'JBUS' + Jump to M if the specified unit is busy. OPCODE = 34, MOD = I/O + unit. +In all the above instructions, the 'MOD' subfile must be in the range +0-20, since it denotes the operation's target device. The 'IOC' +instruction only makes sense for tape devices ('MOD' = 0-7 or 20): it +shifts the read/write pointer by the number of words given by 'M' (if it +equals zero, the tape is rewound)(1) (*note Input-output +operators-Footnote-1::). + + +File: mdk.info, Node: Input-output operators-Footnotes, Up: Input-output operators + + (1) In Knuth's original definition, there are other control +operations available, but they do not make sense when implementing the +block devices as disk files (as we do in MDK simulator).

OPCODE = 5, MOD = 1. +Digits are represented in MIX by the range of values 30-39 (digits 0-9). +Thus, if the contents of 'rA' and 'rX' are, for instance, + + [rA] = + 30 30 31 32 33 + [rX] = + 31 35 39 30 34 +the represented number is 0012315904, and 'NUM' will store this value in +'rA' (i.e., we end up with '[rA]' = + 0 46 62 52 0 = 12315904). + + If any byte in 'rA' or 'rB' does not belong to the range 30-39, it is +interpreted by 'NUM' as the digit obtained by taking its value modulo +10. E.g. values 0, 10, 20, 30, 40, 50, 60 all represent the digit 0; +2, 12, 22, etc. represent the digit 2, and so on.

At +any rate, to compute this asymptotic behaviour, we need a measure of how +long execution of a single instruction takes in our (virtual) CPU. +Therefore, each MIX instruction will have an associated execution time, +given in arbitrary units (in a real computer, the value of this unit +will depend on the hardware configuration). When our MIX virtual +machine executes programs, it will (optionally) give you the value of +their execution time based upon the execution time of each single +instruction. + + In the following table, the execution times (in the above mentioned +arbitrary units) of the MIX instructions are given. + +'NOP' 1 'ADD' 2 'SUB' 2 'MUL' 10 +'DIV' 12 'NUM' 10 'CHAR' 10 'HLT' 10 +'SLx' 2 'SRx' 2 'LDx' 2 'STx' 2 +'JBUS' 1 'IOC' 1 'IN' 1 'OUT' 1 +'JRED' 1 'Jx' 1 'INCx' 1 'DECx' 1 +'ENTx' 1 'ENNx' 1 'CMPx' 1 'MOVE' 1+2F + + In the above table, 'F' stands for the number of blocks to be moved +(given by the 'FSPEC' subfield of the instruction); 'SLx' and 'SRx' are +a short cut for the byte-shifting operations; 'LDx' denote all the +loading operations; 'STx' are the storing operations; 'Jx' stands for +all the jump operations, and so on with the rest of abbreviations. + + +File: mdk.info, Node: MIXAL, Prev: The MIX computer, Up: MIX and MIXAL tutorial + +2.2 MIXAL +========= + +In the previous sections we have listed all the available MIX binary +instructions. As we have shown, each instruction is represented by a +word which is fetched from memory and executed by the MIX virtual CPU. +As is the case with real computers, the MIX knows how to decode +instructions in binary format (the so-called machine language), but a +human programmer would have a tough time if she were to write her +programs in machine language. Fortunately, the MIX computer can be +programmed using an assembly language, MIXAL, which provides a symbolic +way of writing the binary instructions understood by the imaginary MIX +computer. If you have used assembler languages before, you will find +MIXAL a very familiar language. MIXAL source files are translated to +machine language by a MIX assembler, which produces a binary file (the +actual MIX program) which can be directly loaded into the MIX memory and +subsequently executed. + + In this section, we describe MIXAL, the MIX assembly language. The +implementation of the MIX assembler program and MIX computer simulator +provided by MDK are described later on (*note Getting started::). + +* Menu: + +* Basic structure:: Writing basic MIXAL programs. +* MIXAL directives:: Assembler directives. +* Expressions:: Evaluation of expressions. +* W-expressions:: Evaluation of w-expressions. +* Local symbols:: Special symbol table entries. +* Literal constants:: Specifying an immediate operand. + + +File: mdk.info, Node: Basic structure, Next: MIXAL directives, Prev: MIXAL, Up: MIXAL + +2.2.1 Basic program structure +----------------------------- + +The MIX assembler reads MIXAL files line by line, producing, when +required, a binary instruction, which is associated to a predefined +memory address. To keep track of the current address, the assembler +maintains an internal location counter which is incremented each time an +instruction is compiled. In addition to MIX instructions, you can +include in MIXAL file assembly directives (or pseudoinstructions) +addressed at the assembler itself (for instance, telling it where the +program starts and ends, or to reposition the location counter; see +below). + + MIX instructions and assembler directives(1) (*note Basic +structure-Footnote-1::) are written in MIXAL (one per source file line) +according to the following pattern: + + [LABEL] MNEMONIC [OPERAND] [COMMENT] + +where 'OPERAND' is of the form + + [ADDRESS][,INDEX][(MOD)] + + Items between square brackets are optional, and + +'LABEL' + is an alphanumeric identifier (a "symbol") which gets the current + value of the location counter, and can be used in subsequent + expressions, +'MNEMONIC' + is a literal denoting the operation code of the instruction (e.g. + 'LDA', 'STA'; see *note MIX instruction set::) or an assembly + pseudoinstruction (e.g. 'ORG', 'EQU'), +'ADDRESS' + is an expression evaluating to the address subfield of the + instruction, +'INDEX' + is an expression evaluating to the index subfield of the + instruction, which defaults to 0 (i.e., no use of indexing) and can + only be used when 'ADDRESS' is present, +'MOD' + is an expression evaluating to the mod subfield of the instruction. + Its default value, when omitted, depends on 'OPCODE', +'COMMENT' + any number of spaces after the operand mark the beginning of a + comment, i.e. any text separated by white space from the operand + is ignored by the assembler (note that spaces are not allowed + within the 'OPERAND' field). + + Note that spaces are _not_ allowed between the 'ADDRESS', 'INDEX' and +'MOD' fields if they are present. White space is used to separate the +label, operation code and operand parts of the instruction(2) (*note +Basic structure-Footnote-2::). + + We have already listed the mnemonics associated with each MIX +instruction; sample MIXAL instructions representing MIX instructions +are: + HERE LDA 2000 HERE represents the current location counter + LDX HERE,2(1:3) this is a comment + JMP 1234 + + +File: mdk.info, Node: Basic structure-Footnotes, Up: Basic structure + + (1) We shall call them, collectively, MIXAL instructions. + + (2) In fact, Knuth's definition of MIXAL restricts the column number +at which each of these instruction parts must start. The MIXAL +assembler included in MDK, 'mixasm', does not impose such restriction. + + +File: mdk.info, Node: MIXAL directives, Next: Expressions, Prev: Basic structure, Up: MIXAL + +2.2.2 MIXAL directives +---------------------- + +MIXAL instructions can be either one of the MIX machine instructions +(*note MIX instruction set::) or one of the following assembly +pseudoinstructions: + +'ORIG' + Sets the value of the memory address to which following + instructions will be allocated after compilation. +'EQU' + Used to define a symbol's value, e.g. 'SYM EQU 2*200/3'. +'CON' + The value of the given expression is copied directly into the + current memory address. +'ALF' + Takes as operand five characters, constituting the five bytes of a + word which is copied directly into the current memory address. +'END' + Marks the end of the program. Its operand gives the start address + for program execution. + + The operand of 'ORIG', 'EQU', 'CON' and 'END' can be any expression +evaluating to a constant MIX word, i.e., either a simple MIXAL +expression (composed of numbers, symbols and binary operators, *note +Expressions::) or a w-expression (*note W-expressions::). + + All MIXAL programs must contain an 'END' directive, with a twofold +end: first, it marks the end of the assembler job, and, in the second +place, its (mandatory) operand indicates the start address for the +compiled program (that is, the address at which the virtual MIX machine +must begin fetching instructions after loading the program). It is also +very common (although not mandatory) to include at least an 'ORIG' +directive to mark the initial value of the assembler's location counter +(remember that it stores the address associated with each compiled MIX +instruction). Thus, a minimal MIXAL program would be + + ORIG 2000 set the initial compilation address + NOP this instruction will be loaded at address 2000 + HLT and this one at address 2001 + END 2000 end of program; start at address 2000 + this line is not parsed by the assembler +The assembler will generate two binary instructions ('NOP' +(+ 00 00 00 00 00) and 'HLT' (+ 00 00 02 05)), which will be loaded at +addresses 2000 and 2001. Execution of the program will begin at address +2000. Every MIXAL program should also include a 'HLT' instruction, +which will mark the end of program execution (but not of program +compilation). + + The 'EQU' directive allows the definition of symbolic names for +specific values. For instance, we could rewrite the above program as +follows: + + START EQU 2000 + ORIG START + NOP + HLT + END START +which would give rise to the same compiled code. Symbolic constants (or +symbols, for short) can also be implicitly defined placing them in the +'LABEL' field of a MIXAL instruction: in this case, the assembler +assigns to the symbol the value of the location counter before compiling +the line. Hence, a third way of writing our trivial program is + + ORIG 2000 + START NOP + HLT + END START + + The 'CON' directive allows you to directly specify the contents of +the memory address pointed by the location counter. For instance, when +the assembler encounters the following code snippet + + ORIG 1150 + CON -1823473 +it will assign to the memory cell number 1150 the contents +- 00 06 61 11 49 (which corresponds to the decimal value -1823473). + + Finally, the 'ALF' directive lets you specify the memory contents as +a set of five (optionally quoted) characters, which are translated by +the assembler to their byte values, conforming in that way the binary +word that is to be stored in the corresponding memory cell. This +directive comes in handy when you need to store printable messages in a +memory address, as in the following example (1) (*note MIXAL +directives-Footnote-1::): + + OUT MSG MSG is not yet defined here (future reference) + MSG ALF "THIS " MSG gets defined here + ALF "IS A " + ALF "MESSA" + ALF "GE. " +The above snippet also shows the use of a "future reference", that is, +the usage of a symbol ('MSG' in the example) prior of its actual +definition. The MIXAL assembler is able to handle future references +subject to some limitations which are described in the following section +(*note Expressions::). + + Any line starting with an asterisk is treated as a comment and +ignored by the assembler. + + * This is a comment: this line is ignored. + * This line is an error: * must be in column 1. + + As noted in the previous section, comments can also be located after +the 'OPERAND' field of an instruction, separated from it by white space, +as in + + LABEL LDA 100 This is also a comment + + +File: mdk.info, Node: MIXAL directives-Footnotes, Up: MIXAL directives + + (1) In the original MIXAL definition, the 'ALF' argument is not +quoted. You can write the operand (as the 'ADDRESS' field) without +quotes, but, in this case, you must follow the alignment rules of the +original MIXAL definition (namely, the 'ADDRESS' must start at column +17). + + +File: mdk.info, Node: Expressions, Next: W-expressions, Prev: MIXAL directives, Up: MIXAL + +2.2.3 Expressions +----------------- + +The 'ADDRESS', 'INDEX' and 'MOD' fields of a MIXAL instruction can be +expressions, formed by numbers, identifiers and binary operators ('+ - * +/ // :'). '+' and '-' can also be used as unary operators. Operator +precedence is from left to right: there is no other operator precedence +rule, and parentheses cannot be used for grouping. A stand-alone +asterisk denotes the current memory location; thus, for instance, + + 4+2** + +evaluates to 6 (4 plus 2) times the current memory location. White +space is not allowed within expressions. + + The special binary operator ':' has the same meaning as in fspecs, +i.e., + + A:B = 8*A + B +while 'A//B' stands for the quotient of the ten-byte number +'A' 00 00 00 00 00 (that is, A right-padded with 5 null bytes or, what +amounts to the same, multiplied by 64 to the fifth power) divided by +'B'. Sample expressions are: + + 18-8*3 = 30 + 14/3 = 4 + 1+3:11 = 4:11 = 43 + 1//64 = (01 00 00 00 00 00)/(00 00 00 01 00) = (01 00 00 00 00) +Note that all MIXAL expressions evaluate to a MIX word (by definition). + + All symbols appearing within an expression must be previously +defined. Future references are only allowed when appearing standalone +(or modified by an unary operator) in the 'ADDRESS' part of a MIXAL +instruction, e.g. + + * OK: stand alone future reference + STA -S1(1:5) + * ERROR: future reference in expression + LDX 2-S1 + S1 LD1 2000 + + +File: mdk.info, Node: W-expressions, Next: Local symbols, Prev: Expressions, Up: MIXAL + +2.2.4 W-expressions +------------------- + +Besides expressions, as described above (*note Expressions::), the MIXAL +assembler is able to handle the so called "w-expressions" as the +operands of the directives 'ORIG', 'EQU', 'CON' and 'END' (*note MIXAL +directives::). The general form of a w-expression is the following: + + WEXP = EXP[(EXP)][,WEXP] +where 'EXP' stands for an expression and square brackets denote optional +items. Thus, a w-expression is made by an expression, followed by an +optional expression between parenthesis, followed by any number of +similar constructs separated by commas. Sample w-expressions are: + + 2000 + 235(3) + S1+3(S2),3000 + S1,S2(3:5),23 + + W-expressions are evaluated from left to right as follows: + + * Start with an accumulated result 'w' equal to 0. + * Take the first expression of the comma-separated list and evaluate + it. For instance, if the w-expression is 'S1+2(2:4),2000(S2)', we + evaluate first 'S1+2'; let's suppose that 'S1' equals 265230: then + 'S1+2 = 265232 = + 00 01 00 48 16'. + * Evaluate the expression within parenthesis, reducing it to an + f-spec of the form 'L:R'. In our previous example, the expression + between parenthesis already has the desired form: 2:4. + * Substitute the bytes of the accumulated result 'w' designated by + the f-spec using those of the previous expression value. In our + sample, 'w = + 00 00 00 00 00', and we must substitute bytes 2, 3 + and 4 of 'w' using values from 265232. We need 3 bytes, and we + take the least significant ones: 00, 48, and 16, and insert them in + positions 2, 3 and 4 of 'w', obtaining 'w = + 00 00 48 16 00'. + * Repeat this operation with the remaining terms, acting on the new + value of 'w'. In our example, if, say, 'S2 = 1:1', we must + substitute the first byte of 'w' using one byte (the least + significant) from 2000, that is, 16 (since 2000 = + 00 00 00 31 16) + and, therefore, we obtain 'w = + 16 00 48 16 00'; summing up, we + have obtained '265232(1:4),2000(1:1) = + 16 00 48 16 00 = + 268633088'. + + As a second example, in the w-expression + 1(1:2),66(4:5) +we first take two bytes from 1 (00 and 01) and store them as bytes 1 and +2 of the result (obtaining '+ 00 01 00 00 00') and, afterwards, take two +bytes from 66 (01 and 02) and store them as bytes 4 and 5 of the result, +obtaining '+ 00 01 00 01 02' (262210). The process is repeated for each +new comma-separated example. For instance: + + 1(1:1),2(2:2),3(3:3),4(4:4) = 01 02 03 04 00 + + As stated before, w-expressions can only appear as the operands of +MIXAL directives taking a constant value ('ORIG', 'EQU', 'CON' and +'END'). Future references are _not_ allowed within w-expressions (i.e., +all symbols appearing in a w-expression must be defined before it is +used). + + +File: mdk.info, Node: Local symbols, Next: Literal constants, Prev: W-expressions, Up: MIXAL + +2.2.5 Local symbols +------------------- + +Besides user defined symbols, MIXAL programmers can use the so called +"local symbols", which are symbols of the form '[1-9][HBF]'. A local +symbol 'nB' refers to the address of the last previous occurrence of +'nH' as a label, while 'nF' refers to the next 'nH' occurrence. Unlike +user defined symbols, 'nH' can appear multiple times in the 'LABEL' part +of different MIXAL instructions. The following code shows an instance +of local symbols' usage: + + * line 1 + 1H LDA 100 + * line 2: 1B refers to address of line 1, 3F refers to address of line 4 + STA 3F,2(1B//2) + * line 3: redefinition of 1H + 1H STZ + * line 4: 1B refers to address of line 3 + 3H JMP 1B + + Note that a 'B' local symbol never refers to a definition in its own +line, that is, in the following program: + + ORIG 1999 + ST NOP + 3H EQU 69 + 3H ENTA 3B local symbol 3B refers to 3H in previous line + HLT + END ST +the contents of 'rA' is set to 69 and _not_ to 2001.

Literal constants are denoted as '=wexp=', where 'wexp' +is a w-expression (*note W-expressions::). For instance, the code + + L EQU 5 + LDA =20-L= + + causes the assembler to add after the program's end an instruction +with contents 15 ('20-L'), and to assemble the above code as the +instruction ' LDA a', where 'a' stands for the address in which the +value 15 is stored.

As you can see in the above sample, each line in a MIXAL +file can be divided into four fields separated by an arbitrary amount of +whitespace characters (blanks and or tabs). While in Knuth's definition +of MIXAL each field must start at a fixed pre-defined column number, the +MDK assembler loosens this requirement and lets you format the file as +you see fit. The only restrictions retained are for comment lines (like +1-4) which must begin with an asterisk (*) placed at column 1, and for +the label field (see below) which, if present, must also start at column +1. The four fields in each non-comment line are: + + - an optional label, which either refers to the current memory + address (as 'START' and 'MSG' in lines 7 and 9) or a defined symbol + ('TERM') (if present, the label must always start at the first + column in its line, for the first whitespace in the line marks the + beginning of the second field), + - an operation mnemonic, which can represent either a MIX instruction + ('OUT' and 'HLT' in lines 7 and 8 above), or an assembly + pseudoinstruction (e.g., the 'ORIG' pseudoinstruction in line 6(1) + (*note Writing a source file-Footnote-1::). + - an optional operand for the (pseudo)instruction, and + - an optional free text comment. + +Lines 9-12 of the 'hello.mixal' file above also show the second (and +last) difference between Knuth's MIXAL definition and ours: the operand +of the 'ALF' pseudoinstruction (a word of five characters) must be +quoted using ""(2) (*note Writing a source file-Footnote-2::). + + The workings of this sample program should be straightforward if you +are familiar with MIXAL. See TAOCP vol. 1 for a thorough definition or +*note MIX and MIXAL tutorial::, for a tutorial. + + +File: mdk.info, Node: Writing a source file-Footnotes, Up: Writing a source file + + (1) If an 'ORIG' directive is not used, the program will be loaded by +the virtual machine at address 0. 'ORIG' allows allocating the +executable code where you see fit. + + (2) In Knuth's definition, the operand always starts at a fixed +column number, and the use of quotation is therefore unnecessary. As +'mixasm' releases this requirement, marking the beginning and end of the +'ALF' operand disambiguates the parser's recognition of this operand +when it includes blanks. Note that double-quotes (") are not part of +the MIX character set, and, therefore, no escape characters are needed +within 'ALF''s operands. + + +File: mdk.info, Node: Compiling, Next: Running the program, Prev: Writing a source file, Up: Getting started + +3.2 Compiling +============= + +Three simulators of the MIX computer, called 'mixvm', 'gmixvm' and +'mixguile', are included in the MDK tools. They are able to run binary +files containing MIX instructions written in their binary +representation. You can translate MIXAL source files into this binary +form using 'mixasm', the MIXAL assembler. So, in order to compile the +'hello.mixal' file, you can type the following command at your shell +prompt: + + mixasm hello <RET> + + If the source file contains no errors, this will produce a binary +file called 'hello.mix' which can be loaded and run by the MIX virtual +machine. Unless the 'mixasm' option '-O' is provided, the assembler +will include debug information in the executable file (for a complete +description of all the compilation options, see *note mixasm::). Now, +your are ready to run your first MIX program, as described in the +following section. + + +File: mdk.info, Node: Running the program, Next: Using mixguile, Prev: Compiling, Up: Getting started + +3.3 Running the program +======================= + +MIX is a mythical computer, so it is no use ordering it from your +favorite hardware provider. MDK provides three software simulators of +the computer, though. They are + + * 'mixvm', a command line oriented simulator, + * 'gmixvm', a GTK based graphical interface to 'mixvm', and + * 'mixguile', a Guile shell with a built-in MIX simulator. + + All three simulators accept the same set of user commands, but offer +a different user interface, as noted above. In this section we shall +describe some of these commands, and show you how to use them from +'mixvm''s command line. You can use them as well at 'gmixvm''s command +prompt (*note gmixvm::), or using the built-in Scheme primitives of +'mixguile' (*note Using mixguile::). + + Using the MIX simulators, you can run your MIXAL programs, after +compiling them with 'mixasm' into binary '.mix' files. 'mixvm' can be +used either in "interactive" or "non-interactive" mode. In the second +case, 'mixvm' will load your program into memory, execute it (producing +any output due to MIXAL 'OUT' instructions present in the program), and +exit when it encounters a 'HLT' instruction. In interactive mode, you +will enter a shell prompt which allows you issuing commands to the +running virtual machine. These commands will permit you to load, run +and debug programs, as well as to inspect the MIX computer state +(register contents, memory cells contents and so on). + +* Menu: + +* Non-interactive mode:: Running your programs non-interactively. +* Interactive mode:: Running programs interactively. +* Debugging:: Commands for debugging your programs. + + +File: mdk.info, Node: Non-interactive mode, Next: Interactive mode, Prev: Running the program, Up: Running the program + +3.3.1 Non-interactive mode +-------------------------- + +To make 'mixvm' work in non-interactive mode, use the '-r' flag. Thus, +to run our 'hello.mix' program, simply type + + mixvm -r hello <RET> + +at your command prompt, and you will get the following output: + + MIXAL HELLO WORLD + +Since our hello world program uses MIX's device number 19 as its output +device (*note Writing a source file::), the output is redirected to the +shell's standard output. Had you used any other MIX output devices +(disks, drums, line printer, etc.), 'mixvm' would have created a file +named after the device used (e.g. 'disk4.dev') and written its output +there(1) (*note Non-interactive mode-Footnote-1::). + + The virtual machine can also report the execution time of the +program, according to the (virtual) time spent in each of the binary +instructions (*note Execution times::). Printing of execution time +statistics is activated with the '-t' flag; running + + mixvm -t -r hello <RET> + +produces the following output: + + MIXAL HELLO WORLD + ** Execution time: 11 + + Sometimes, you will prefer to store the results of your program in +MIX registers rather than writing them to a device. In such cases, +'mixvm''s '-d' flag is your friend: it makes 'mixvm' dump the contents +of its registers and flags after executing the loaded program. For +instance, typing the following command at your shell's prompt + + mixvm -d -r hello + +you will obtain the following output: + + MIXAL HELLO WORLD + rA: + 00 00 00 00 00 (0000000000) + rX: + 00 00 00 00 00 (0000000000) + rJ: + 00 00 (0000) + rI1: + 00 00 (0000) rI2: + 00 00 (0000) + rI3: + 00 00 (0000) rI4: + 00 00 (0000) + rI5: + 00 00 (0000) rI6: + 00 00 (0000) + Overflow: F + Cmp: E + +which, in addition to the program's outputs and execution time, gives +you the contents of the MIX registers and the values of the overflow +toggle and comparison flag (admittedly, rather uninteresting in our +sample). + + As you can see, running programs non-interactively has many +limitations. You cannot peek the virtual machine's memory contents, not +to mention stepping through your program's instructions or setting +breakpoints(2) (*note Non-interactive mode-Footnote-2::). Enter +interactive mode. + + +File: mdk.info, Node: Non-interactive mode-Footnotes, Up: Non-interactive mode + + (1) The device files are stored, by default, in a directory called +'.mdk', which is created in your home directory the first time 'mixvm' +is run. You can change this default directory using the command +'devdir' when running 'mixvm' in interactive mode (*note Configuration +commands::) + + (2) The 'mixguile' program allows you to execute arbitrary +combinations of 'mixvm' commands (using Scheme) non-interactively. +*Note Scheme scripts::. + + +File: mdk.info, Node: Interactive mode, Next: Debugging, Prev: Non-interactive mode, Up: Running the program + +3.3.2 Interactive mode +---------------------- + +To enter the MIX virtual machine interactive mode, simply type + + mixvm <RET> + +at your shell command prompt.

Use 'next' to step through the +program, running its instructions one by one. To run our +two-instruction 'hello.mix' sample you can do the following: + + MIX > load hello + Program loaded. Start address: 3000 + MIX > pc + Current address: 3000 + MIX > next + MIXAL HELLO WORLD + Elapsed time: 1 /Total program time: 1 (Total uptime: 1) + MIX > pc + Current address: 3001 + MIX > next + End of program reached at address 3002 + Elapsed time: 10 /Total program time: 11 (Total uptime: 11) + MIX > pc + Current address: 3002 + MIX > next + MIXAL HELLO WORLD + Elapsed time: 1 /Total program time: 1 (Total uptime: 12) + MIX > + MIX > run + Running ... + ... done + Elapsed time: 10 /Total program time: 11 (Total uptime: 22) + MIX > +(As an aside, the above sample also shows how the virtual machine +handles cumulative time statistics and automatic program restart). + + You can set a breakpoint at a given address using the command 'sbpa' +(set breakpoint at address). When a breakpoint is set, 'run' will stop +before executing the instruction at the given address. Typing 'run' +again will resume program execution. Coming back to our hello world +example, we would have: + + MIX > sbpa 3001 + Breakpoint set at address 3001 + MIX > run + Running ... + MIXAL HELLO WORLD + ... stopped: breakpoint at line 8 (address 3001) + Elapsed time: 1 /Total program time: 1 (Total uptime: 23) + MIX > run + Running ... + ... done + Elapsed time: 10 /Total program time: 11 (Total uptime: 33) + MIX > + +Note that, since we compiled 'hello.mixal' with debug info enabled, the +virtual machine is able to tell us the line in the source file +corresponding to the breakpoint we are setting. As a matter of fact, +you can directly set breakpoints at source code lines using the command +'sbp LINE_NO', e.g. + + MIX > sbp 4 + Breakpoint set at line 7 + MIX > + +'sbp' sets the breakpoint at the first meaningful source code line; +thus, in the above example we have requested a breakpoint at a line +which does not correspond to a MIX instruction and the breakpoint is set +at the first line containing a real instruction after the given one. To +unset breakpoints, use 'cbpa ADDRESS' and 'cbp LINE_NO', or 'cabp' to +remove all currently set breakpoints. You can also set conditional +breakpoints, i.e., tell 'mixvm' to interrupt program execution whenever +a register, a memory cell, the comparison flag or the overflow toggle +change using the commands 'sbp[rmco]' (*note Debug commands::). + + MIXAL lets you define symbolic constants, either using the 'EQU' +pseudoinstruction or starting an instruction line with a label (which +assigns to the label the value of the current memory address). Each +MIXAL program has, therefore, an associated symbol table which you can +inspect using the 'psym' command. For our hello world sample, you will +obtain the following output: + + MIX > psym + START: 3000 + TERM: 19 + MSG: 3002 + MIX > + + Other useful commands for debugging are 'strace' (which turns on +tracing of executed instructions), 'pbt' (which prints a backtrace of +executed instructions) and 'weval' (which evaluates w-expressions on the +fly). For a complete description of all available MIX commands, *Note +mixvm::. + + +File: mdk.info, Node: Using mixguile, Next: Using Scheme in mixvm and gmixvm, Prev: Running the program, Up: Getting started + +3.4 Using 'mixguile' +==================== + +With 'mixguile' you can run a MIX simulator embedded in a Guile shell, +that is, using Scheme functions and programs. As with 'mixvm', +'mixguile' can be run both in interactive and non-interactive modes. +The following subsections provide a quick tour on using this MIX +emulator. + +* Menu: + +* The mixguile shell:: Using the Scheme MIX virtual machine. +* Additional functions:: Scheme functions accessing the VM. +* Defining new functions:: Defining your own Scheme functions. +* Hook functions:: Using command and break hook functions. +* Scheme scripts:: + + +File: mdk.info, Node: The mixguile shell, Next: Additional functions, Prev: Using mixguile, Up: Using mixguile + +3.4.1 The 'mixguile' shell +-------------------------- + +If you simply type + + mixguile <RET> +at the command prompt, you'll be presented a Guile shell prompt like +this + + guile> +At this point, you have entered a Scheme read-eval-print loop (REPL) +which offers you all the Guile functionality plus a new set of built-in +procedures to execute and debug MIX programs. Each of the 'mixvm' +commands described in the previous sections (and in *note mixvm::) have +a Scheme function counterpart named after it by prepending the prefix +'mix-' to its name. Thus, to load our hello world program, you can +simply enter + + guile> (mix-load "hello") + Program loaded. Start address: 3000 + guile> +and run it using 'mix-run': + + guile> (mix-run) + Running ... + MIXAL HELLO WORLD + ... done + Elapsed time: 11 /Total program time: 11 (Total uptime: 11) + guile> +In the same way, you can execute it step by step using the Scheme +function 'mix-next' or set a breakpoint: + + guile> (mix-sbp 4) + Breakpoint set at line 5 + guile> +or, if you one to peek at a register contents: + + guile> (mix-preg 'A) + rA: + 00 00 00 00 00 (0000000000) + guile> + + You get the idea: you have at your disposal all the 'mixvm' and +'gmixvm' commands by means of 'mix-' functions. But, in case you are +wondering, this is only the beginning. You also have at your disposal a +whole Scheme interpreter, and you can, for instance, define new +functions combining the 'mix-' and all other Scheme primitives. In the +next sections, you'll find examples of how to take advantage of the +Guile interpreter. + + +File: mdk.info, Node: Additional functions, Next: Defining new functions, Prev: The mixguile shell, Up: Using mixguile + +3.4.2 Additional MIX Scheme functions +------------------------------------- + +The 'mix-' function counterparts of the 'mixvm' commands don't return +any value, and are evaluated only for their side-effects (possibly +including informational messages to the standard output and/or error +stream). When writing your own Scheme functions to manipulate the MIX +virtual machine within 'mixguile' (*note Defining new functions::), +you'll probably need Scheme functions returning the value of the +registers, memory cells and so on. Don't worry: 'mixguile' also offers +you such functions. For instance, to access the (numerical) value of a +register you can use 'mix-reg': + + guile> (mix-reg 'I2) + 0 + guile> +Note that, unlike '(mix-preg 'I2)', the expression '(mix-reg 'I2)' in +the above example evaluates to a Scheme number and does not produce any +side-effect: + + guile> (number? (mix-reg 'I2)) + #t + guile> (number? (mix-preg 'I2)) + rI2: + 00 00 (0000) + #f + guile> + + In a similar fashion, you can access the memory contents using +'(mix-cell)', or the program counter using '(mix-loc)': + + guile> (mix-cell 3000) + 786957541 + guile> (mix-loc) + 3002 + guile> + + Other functions returning the contents of the virtual machine +components are 'mix-cmp' and 'mix-over', which eval to the value of the +comparison flag and the overflow toggle respectively. For a complete +list of these additional functions, *Note mixguile::. + + In the next section, we'll see a sample of using these functions to +extend 'mixguile''s functionality. + + +File: mdk.info, Node: Defining new functions, Next: Hook functions, Prev: Additional functions, Up: Using mixguile + +3.4.3 Defining new functions +---------------------------- + +Scheme is a powerful language, and you can use it inside 'mixguile' to +easily extend the MIX interpreter's capabilities. For example, you can +easily define a function that loads a file, prints its name, executes it +and, finally, shows the registers contents, all in one shot: + + guile> (define my-load-and-run <RET> + (lambda (file) <RET> + (mix-load file) <RET> + (display "File loaded: ") <RET> + (mix-pprog) <RET> + (mix-run) <RET> + (mix-preg))) <RET> + guile> +and use it to run your programs: + + guile> (my-load-and-run "hello") + Program loaded. Start address: 3000 + File loaded: hello.mix + Running ... + MIXAL HELLO WORLD + ... done + Elapsed time: 11 /Total program time: 11 (Total uptime: 33) + rA: + 00 00 00 00 00 (0000000000) + rX: + 00 00 00 00 00 (0000000000) + rJ: + 00 00 (0000) + rI1: + 00 00 (0000) rI2: + 00 00 (0000) + rI3: + 00 00 (0000) rI4: + 00 00 (0000) + rI5: + 00 00 (0000) rI6: + 00 00 (0000) + guile> + + Or, maybe, you want a function which sets a breakpoint at a specified +line number before executing it: + + guile> (define my-load-and-run-with-bp + (lambda (file line) + (mix-load file) + (mix-sbp line) + (mix-run))) + guile> (my-load-and-run-with-bp "samples/primes" 10) + Program loaded. Start address: 3000 + Breakpoint set at line 10 + Running ... + ... stopped: breakpoint at line 10 (address 3001) + Elapsed time: 1 /Total program time: 1 (Total uptime: 45) + guile> + + As a third example, the following function loads a program, runs it +and prints the contents of the memory between the program's start and +end addresses: + + guile> (define my-run + (lambda (file) + (mix-load file) + (let ((start (mix-loc))) + (mix-run) + (mix-pmem start (mix-loc))))) + guile> (my-run "hello") + Program loaded.

Of +course, you don't need to type a function definition each time you start +'mixguile'. You can write it in a file, and load it using Scheme's +'load' function. For instance, you can create a file named, say, +'functions.scm' with your definitions (or any Scheme expression) and +load it at the 'mixguile' prompt: + + guile> (load "functions.scm") + + Alternatively, you can make 'mixguile' to load it for you. When +'mixguile' starts, it looks for a file named 'mixguile.scm' in your MDK +configuration directory ('~/.mdk') and, if it exists, loads it before +entering the REPL. Therefore, you can copy your definitions in that +file, or load the 'functions.scm' file in 'mixguile.scm'. + + +File: mdk.info, Node: Hook functions, Next: Scheme scripts, Prev: Defining new functions, Up: Using mixguile + +3.4.4 Hook functions +-------------------- + +Hooks are functions called before or after a given event occurs. In +'mixguile', you can define command and break hooks, which are +associated, respectively, with command execution and program +interruption events. The following sections give you a tutorial on +using hook functions within 'mixguile'. + +* Menu: + +* Command hooks:: +* Break hooks:: + + +File: mdk.info, Node: Command hooks, Next: Break hooks, Prev: Hook functions, Up: Hook functions + +3.4.4.1 Command hooks +..................... + +In the previous section, we have seen how to extend 'mixguile''s +functionality through the use of user defined functions. Frequently, +you'll write new functions that improve in some way the workings of a +built-in 'mixvm' command, following this pattern: + + a. Prepare the command execution + b. Execute the desired command + c. Perform post execution operations + + We call the functions executed in step (a) "pre-hook"s, and those of +step "post-hook"s of the given command. 'mixguile' lets you specify +pre- and post-hooks for any 'mixvm' command using the 'mix-add-pre-hook' +and 'mix-add-post-hook' functions, which take as arguments a symbol +naming the command and a function to be executed before (resp. after) +the command. In other words, 'mixguile' will execute for you steps (a) +and (c) above whenever you eval (b). The hook functions must take a +single argument, which is a string list of the command's arguments. As +an example, let us define the following hooks for the 'next' command: + + (define next-pre-hook + (lambda (arglist) + (mix-slog #f))) + + (define next-post-hook + (lambda (arglist) + (display "Stopped at line ") + (display (mix-src-line-no)) + (display ": ") + (display (mix-src-line)) + (newline) + (mix-slog #t))) +In these functions, we are using the function 'mix-slog' to turn off the +informational messages produced by the virtual machine, since we are +providing our own ones in the post hook function. To install these +hooks, we would write: + + (mix-add-pre-hook 'next next-pre-hook) + (mix-add-post-hook 'next next-post-hook) +Assuming we have put the above expressions in 'mixguile''s +initialisation file, we would obtain the following results when +evaluating 'mix-next': + + guile> (mix-next) + MIXAL HELLO WORLD + Stopped at line 6: HLT + guile> + + As a second, more elaborate, example, let's define hooks which print +the address and contents of a cell being modified using 'smem'. The +hook functions could be something like this: + + (define smem-pre-hook + (lambda (arglist) + (if (eq? (length arglist) 2) + (begin + (display "Changing address ") + (display (car arglist)) + (newline) + (display "Old contents: ") + (display (mix-cell (string->number (car arglist)))) + (newline)) + (error "Wrong arguments" arglist)))) + + (define smem-post-hook + (lambda (arglist) + (if (eq? (length arglist) 2) + (begin + (display "New contents: ") + (display (mix-cell (string->number (car arglist)))) + (newline))))) +and we can install them using + + (mix-add-pre-hook 'smem smem-pre-hook) + (mix-add-post-hook 'smem smem-post-hook) +Afterwards, a sample execution of 'mix-smem' would look like this: + + guile> (mix-smem 2000 100) + Changing address 2000 + Old contents: 0 + New contents: 100 + guile> + + You can add any number of hooks to a given command. They will be +executed in the same order as they are registered. You can also define +global post (pre) hooks, which will be called before (after) any 'mixvm' +command is executed. Global hook functions must admit two arguments, +namely, a string naming the invoked command and a string list of its +arguments, and they are installed using the Scheme functions +'mix-add-global-pre-hook' and 'mix-add-global-post-hook'. A simple +example of global hook would be: + + guile> (define pre-hook + (lambda (cmd args) + (display cmd) + (display " invoked with arguments ") + (display args) + (newline))) + guile> (mix-add-global-pre-hook pre-hook) + ok + guile> (mix-pmem 120 125) + pmem invoked with arguments (120-125) + 0120: + 00 00 00 00 00 (0000000000) + 0121: + 00 00 00 00 00 (0000000000) + 0122: + 00 00 00 00 00 (0000000000) + 0123: + 00 00 00 00 00 (0000000000) + 0124: + 00 00 00 00 00 (0000000000) + 0125: + 00 00 00 00 00 (0000000000) + guile> + + Note that if you invoke 'mixvm' commands within a global hook, its +associated command hooks will be run. Thus, if you have installed both +the 'next' hooks described earlier and the global hook above, executing +'mix-next' will yield the following result: + + guile> (mix-next 5) + next invoked with arguments (5) + slog invoked with arguments (off) + MIXAL HELLO WORLD + Stopped at line 7: MSG ALF "MIXAL" + slog invoked with arguments (on) + guile> + + Adventurous readers may see the above global hook as the beginning of +a command log utility or a macro recorder that saves your commands for +replay. + + +File: mdk.info, Node: Break hooks, Prev: Command hooks, Up: Hook functions + +3.4.4.2 Break hooks +................... + +We have seen in the previous section how to associate hooks to command +execution, but they are not the whole story. You can also associate +hook functions to program interruption, that is, specify functions that +should be called every time the execution of a MIX program is stopped +due to the presence of a breakpoint, either explicit or conditional. +Break hooks take as arguments the line number and memory address at +which the break occurred. A simple hook that logs the line and address +of the breakpoint could be defined as: + + (define break-hook + (lambda (line address) + (display "Breakpoint encountered at line ") + (display line) + (display " and address ") + (display address) + (newline))) +and installed for explicit and conditional breakpoints using + + (mix-add-break-hook break-hook) + (mix-add-cond-break-hook break-hook) +after that, every time the virtual machine encounters a breakpoint, +'break-code' shall be evaluated for you(1) (*note Break +hooks-Footnote-1::). + + +File: mdk.info, Node: Break hooks-Footnotes, Up: Break hooks + + (1) You may have noticed that break hooks can be implemented in terms +of command hooks associated to 'mix-run' and 'mix-next'. As a matter of +fact, they _are_ implemented this way: take a look at the file +'_install_dir_/share/mdk/mix-vm-stat.scm' if you are curious. + + +File: mdk.info, Node: Scheme scripts, Prev: Hook functions, Up: Using mixguile + +3.4.5 Scheme scripts +-------------------- + +Another useful way of using 'mixguile' is writing executable scripts +that perform a set of commands for you. This is done using the +'mixguile' switch '-s' (being a Guile shell, 'mixguile' accepts all the +command options of 'guile'; type 'mixguile -h' for a list of all +available command options). For instance, if you have a very useful MIX +program 'foo.mix' which you want to run often, you don't have to fire up +a MIX virtual machine, load and run it every time; you can write a +Scheme script instead: + + #! /usr/bin/mixguile -s + !# + ;;; runprimes: execute the primes.mix program + + ;; load the file you want to run + (mix-load "../samples/primes") + ;; execute it + (mix-run) + ;; print the contents of registers + (mix-pall) + ;; ... + + Just save the above script to a file named, say, 'runtest', make it +executable ('chmod +x runtest'), and, well, execute it from the Unix +shell: + + $ ./runtest + Program loaded.

This possibility is not limited to the +'mixguile' shell. Actually, both 'mixvm' and 'gmixvm' incorporate an +embedded Guile interpreter, and can evaluate Scheme expressions. To +evaluate a single-line expression at the 'mixvm' or 'gmixvm' command +prompt, simply write it and press return (the command parser will +recognise it as a Scheme expression because it is parenthesized, and +will pass it to the Guile interpreter).

This can be done with the MIX virtual machine. First you will need +to compile your code into MIX byte code. This can be done within Emacs +with the command 'M-x compile' ('C-c c'). In case of compilation +errors, you can jump to the offending source code line with 'M-x +next-error'. + + Once the program compiles without errors, you can debug or run it. +To invoke the debugger, use 'M-x mixal-debug' ('C-c d'). Emacs will +open a 'GUD' buffer where you can use the debugging commands described +in *Note mixvm::. + + If you just want to execute the program, you can do so with 'M-x +mixal-run' ('C-c r'). This will invoke mixvm, execute the program and +show its output in a separate buffer. + + +File: mdk.info, Node: GUD integration, Prev: MIXAL mode, Up: Emacs tools + +4.2 GUD integration +=================== + +If you are an Emacs user and write your MIXAL programs using this +editor, you will find the elisp program 'mixvm.el' quite useful(1) +(*note GUD integration-Footnote-1::). 'mixvm.el' allows running the MIX +virtual machine 'mixvm' (*note mixvm::) inside an Emacs GUD buffer, +while visiting the MIXAL source file in another buffer. + + After installing 'mixvm.el' (*note Emacs support::), you can initiate +an MDK/GUD session inside Emacs with the command + + M-x mixvm + +and you will have a 'mixvm' prompt inside a newly created GUD buffer. +GUD will reflect the current line in the corresponding source file +buffer. + + +File: mdk.info, Node: GUD integration-Footnotes, Up: GUD integration + + (1) 'mixvm.el' has been kindly contributed by Philip E.

If the optional FILE +argument is given, the file 'FILE.mix' will be loaded into the virtual +machine memory before entering the interactive mode. + + The first time 'mixvm' is invoked, a directory named '.mdk' is +created in your home directory. It contains the 'mixvm' configuration +file, the command history file and (by default) the block devices files +(*note Devices::). Before showing you the command prompt, 'mixvm' looks +in the '~/.mdk' directory for a file named 'mixguile.scm'; if it exists, +it is read and evaluated by the embedded Guile interpreter (*note +Defining new functions::).

You will then be greeted by a shell +prompt(1) (*note Commands-Footnote-1::) + + MIX > + +which indicates that a new virtual machine has been initialised and is +ready to execute your commands. As we have already mentioned, this +command prompt offers you command line editing facilities which are +described in the Readline user's manual (chances are that you are +already familiar with these command line editing capabilities, as they +are present in many GNU utilities, e.g. the 'bash' shell)(2) (*note +Commands-Footnote-2::). In a nutshell, readline provides command +completion using the 'TAB' key and command history using the cursor +keys. A history file containing the last commands typed in previous +sessions is stored in the MDK configuration directory ('~/.mdk'). + + As a beginner, your best friend will be the 'help' command, which +shows you a summary of all available MIX commands and their usage; its +syntax is as follows: + + -- 'mixvm' command: help [command] + Prints a short description of the given COMMAND and its usage.

This address is indicated in the MIXAL source file + as the operand of the 'END' pseudoinstruction. Thus, if your + 'sample.mixal' source file contains the line: + + END 3000 + + and you compile it with 'mixasm' to produce the binary file + 'sample.mix', you will load it into the virtual machine as follows: + + MIX > load sample + Program loaded. Start address: 3000 + MIX > + + -- file command: run [file[.mix]] + When executed without argument, this command initiates or resumes + execution of instructions from the current program counter address. + Therefore, issuing this command after a successful 'load', will run + the loaded program until either a 'HLT' instruction or a breakpoint + is found. If you provide a MIX filename as argument, the given + file will be loaded (as with 'load' FILE) and executed. If 'run' + is invoked again after program execution completion (i.e., after + the 'HLT' instruction has been found in a previous run), the + program counter is repositioned and execution starts again from the + beginning (as a matter of fact, a 'load' command preserving the + currently set breakpoints is issued before resuming execution). + + -- file command: edit [file[.mixal]] + The source file FILE.MIXAL is edited using the editor defined in + the environment variable MDK_EDITOR. If this variable is not set, + the following ones are tried out in order: X_EDITOR, EDITOR and + VISUAL. If invoked without argument, the source file for the + currently loaded MIX file is edited. The command used to edit + source files can also be configured using the 'sedit' command + (*note Configuration commands::). + + -- file command: compile file[.mixal] + The source file FILE.MIXAL is compiled (with debug information + enabled) using 'mixasm'. If invoked without argument, the source + file for the currently loaded MIX file is recompiled. The + compilation command can be set using the 'sasm' command (*note + Configuration commands::). + + -- file command: pprog + -- file command: psrc + Print the path of the currently loaded MIX program and its source + file: + + MIX > load ../samples/primes + Program loaded.

Execution is interrupted either when the specified + number of instructions have been fetched or a breakpoint is found, + whatever happens first. If run without arguments, one instruction + is executed. If 'next' is invoked again after program execution + completion (i.e., after the 'HLT' instruction has been found in a + previous run), the program counter is repositioned and execution + starts again from the beginning (as a matter of fact, a 'load' + command preserving the currently set breakpoints is issued before + resuming execution). + + -- debug command: sbp line_number + -- debug command: cbp line_no + Sets a breakpoint at the specified source file line number. If the + line specified corresponds to a command or to a MIXAL + pseudoinstruction which does not produce a MIX instruction in the + binary file (such as 'ORIG' or 'EQU') the breakpoint is set at the + first source code line giving rise to a MIX instruction after the + specified one. Thus, for our sample 'hello.mixal' file: + + * (1) + * hello.mixal: say 'hello world' in MIXAL (2) + * (3) + * label ins operand comment (4) + TERM EQU 19 the MIX console device number (5) + ORIG 1000 start address (6) + START OUT MSG(TERM) output data at address MSG (7) + ... + + trying to set a breakpoint at line 5, will produce the following + result: + + MIX > sbp 5 + Breakpoint set at line 7 + MIX > + + since line 7 is the first one compiled into a MIX instruction (at + address 3000). + + The command 'cbp' clears a (previously set) breakpoint at the given + source file line. + + -- debug command: spba address + -- debug command: cbpa address + Sets a breakpoint at the given memory ADDRESS. The argument must + be a valid MIX memory address, i.e., it must belong into the range + [0-3999]. Note that no check is performed to verify that the + specified address is reachable during program execution. No debug + information is needed to set a breakpoint by address with 'sbpa'. + The command 'cbpa' clears a (previously set) breakpoint at the + given memory address. + + -- debug command: sbpr A | X | J | Ii + -- debug command: cbpr A | X | J | Ii + Sets a conditional breakpoint on the specified register change. + For instance, + + sbpr I1 + + will cause an interruption during program execution whenever the + contents of register 'I1' changes. A previously set breakpoint is + cleared using the 'cbpr' command. + + -- debug command: sbpm address + -- debug command: cbpm address + Sets a conditional breakpoint on the specified memory cell change. + The argument must be a valid MIX memory address, i.e., it must + belong into the range [0-3999]. For instance, + + sbpm 1000 + + will cause an interruption during program execution whenever the + contents of the memory cell number 1000 changes. A previously set + breakpoint is cleared using the 'cbpm' command. + + -- debug command: sbpo + -- debug command: cbpo + Sets/clears a conditional breakpoint on overflow toggle change. + + -- debug command: sbpc + -- debug command: cbpc + Sets/clears a conditional breakpoint on comparison flag change. + + -- debug command: cabp + Clears all currently set breakpoints. + + -- debug command: psym [symbol_name] + MIXAL programs can define symbolic constants, using either the + 'EQU' pseudoinstruction or a label at the beginning of a line. + Thus, in the program fragment + + VAR EQU 2168 + ORIG 4000 + START LDA VAR + + the symbol 'VAR' stands for the value 2168, while 'START' is + assigned the value 4000. The symbol table can be consulted from + the 'mixvm' command line using 'psym' followed by the name of the + symbol whose contents you are interested in. When run without + arguments, 'psym' will print all defined symbols and their values. + + The virtual machine can also show you the instructions it is +executing, using the following commands: + + -- debug command: strace [on|off] + 'strace on' enables instruction tracing. When tracing is enabled, + each time the virtual machine executes an instruction (due to your + issuing a 'run' or 'next' command), it is printed in its canonical + form (that is, with all expressions evaluated to their numerical + values) and, if the program was compiled with debug information, as + it was originally typed in the MIXAL source file. Instruction + tracing is disabled with 'strace off' command. A typical tracing + session could be like this: + + MIX > strace on + MIX > next + 3000: [OUT 3002,0(2:3)] START OUT MSG(TERM) + MIXAL HELLO WORLD + Elapsed time: 1 /Total program time: 1 (Total uptime: 1) + MIX > next + 3001: [HLT 0,0] HLT + End of program reached at address 3002 + Elapsed time: 10 /Total program time: 11 (Total uptime: 11) + MIX > strace off + MIX > + The executed instruction, as it was translated, is shown between + square brackets after the memory address, and, following it, you + can see the actual MIXAL code that was compiled into the executed + instruction. The tracing behaviour is stored as a configuration + parameter in '~/.mdk'. + + -- debug command: pline [LINE_NUMBER] + Prints the requested source line (or the current one if LINE_NUMBER + is omitted: + + MIX > load ../samples/hello + Program loaded. Start address: 3000 + MIX > pline + Line 5: START OUT MSG(TERM) + MIX > pline 6 + Line 6: HLT + MIX > + + -- debug command: pbt [INS_NUMBER] + This command prints a backtrace of executed instructions. Its + optional argument INS_NUMBER is the number of instructions to + print. If it is omitted or equals zero, all executed instructions + are printed. For instance, if you compile and load the following + program ('bt.mixal'): + + ORIG 0 + BEG JMP *+1 + JMP *+1 + FOO JMP BAR + BAR HLT + END BEG + + you could get the following traces: + + MIX > load bt + Program loaded.

This behaviour can be controlled using the 'stime' +command (*note Configuration commands::). + + 'mixvm' is also able of evaluating w-expressions (*note +W-expressions::) using the following command: + + -- debug command: weval WEXP + Evaluates the given w-expression, WEXP. The w-expression can + contain any currently defined symbol. For instance: + + MIX > psym START + + 00 00 00 46 56 (0000003000) + MIX > weval START(0:1),START(3:4) + + 56 00 46 56 00 (0939716096) + MIX > + + New symbols can be defined using the 'ssym' command: + + -- debug command: ssym SYM WEXP + Defines the symbol named SYM with the value resulting from + evaluating WEXP, a w-expression. The newly defined symbol can be + used in subsequent 'weval' commands, as part of the expression to + be evaluated. E.g., + + MIX > ssym S 2+23*START + + 00 00 18 19 56 (0000075000) + MIX > psym S + + 00 00 18 19 56 (0000075000) + MIX > weval S(3:4) + + 00 00 19 56 00 (0000081408) + MIX > + + Finally, if you want to discover which is the decimal value of a MIX +word expressed as five bytes plus sign, you can use + + -- debug command: w2d WORD + Computes the decimal value of the given word. WORD must be + expressed as a sign (+/-) followed by five space-delimited, + two-digit decimal values representing the five bytes composing the + word. The reverse operation (showing the word representation of a + decimal value) can be accomplished with 'weval'. For instance: + + MIX > w2d - 01 00 00 02 02 + -16777346 + MIX > weval -16777346 + - 01 00 00 02 02 (0016777346) + MIX > + + +File: mdk.info, Node: State commands, Next: Configuration commands, Prev: Debug commands, Up: Commands + +6.2.3 State commands +-------------------- + +Inspection and modification of the virtual machine state (memory, +registers, overflow toggle and comparison flag contents) is accomplished +using the following commands: + + -- state command: pstat + This commands prints the current virtual machine state, which can + be one of the following: + - No program loaded + - Program successfully loaded + - Execution stopped ('next' executed) + - Execution stopped: breakpoint encountered + - Execution stopped: conditional breakpoint encountered + - Program successfully terminated + + -- state command: pc + Prints the current value of the program counter, which stores the + address of the next instruction to be executed in a non-halted + program. + + -- state command: sreg A | X | J | I[1-6] value + -- state command: preg [A | X | J | I[1-6]] + -- state command: pall + 'preg' prints the contents of a given MIX register.

When you request an output operation on any +other (output) device, a file named according to the following table +will be created, and the specified MIX words will be written to the file +in binary form (for binary devices) or in ASCII (for char devices). +Files corresponding to input block devices should be created and filled +beforehand to be used by the MIX virtual machine (for input-output +devices this creation can be accomplished by a MIXAL program writing to +the device the required data, or, if you prefer, with your favourite +editor).

For instance, since the card reader has blocks of size 16, that +is, 80 characters, it will be emulated by an ASCII file consisting of +lines with length 80. If the reader finds a line with less than the +required number of characters, it pads the memory with zeroes (MIX +character 'space') to complete the block size. + + Note that the virtual machine automatically converts between the MIX +and ASCII character encodings, so that you can manipulate char device +files with any ASCII editor. In addition, the reader is not +case-sensitive, i.e., it automatically converts lowercase letters to +their uppercase counterparts (since the MIX character set does not +include the former). + + The typewriter (device no. 19) lets you use the standard input and +output in your MIXAL programs. For instance, here is a simple 'echo' +program: + + * simple echo program + TERM EQU 19 the typewriter device + BUF EQU 500 input buffer + ORIG 1000 + START IN BUF(TERM) read a block (70 chars) + OUT BUF(TERM) write the read chars + HLT + END START + +Input lines longer than 70 characters (14 words) are trimmed.

In the upper half of 'gmixvm''s main +window there is a notebook with three pages, namely, + + * a MIX virtual machine view, which shows you the registers, flags, + memory contents and time statistics of the virtual machine; + * a MIXAL source view, which shows the MIXAL file and lets you manage + breakpoints; + * a Devices view, which shows you the output to character based MIX + block devices. + +These three windows can be detached from the notebook, using either the +penultimate toolbar button (which detachs the currently visible notebook +page) or the menu entries under 'View->Detached windows'. + + On the other hand, the main window's lower half presents you a +'mixvm' command prompt and a logging area where results of the issued +commands are presented. These widgets implement a 'mixvm' console which +offers almost the same functionality as its CLI counterpart. + + When 'gmixvm' is run, it creates a directory named '.mdk' in your +home directory (if it does not already exist). The '.mdk' directory +contains the program settings, the device files used by your MIX +programs (*note Devices::), and a command history file. + + The following sections describe the above mentioned components of +'gmixvm'. + + +File: mdk.info, Node: MIXVM console, Next: MIX virtual machine, Prev: Invoking gmixvm, Up: gmixvm + +7.2 MIXVM console +================= + +In the lower half of the 'gmixvm' main window, you will find a command +text entry and, above it, an echo area. These widgets offer you the +same functionality as its CLI counterpart, 'mixvm' (*note mixvm::). You +can issue almost all 'mixmv' commands at the 'gmixvm''s command prompt +in order to manipulate the MIX virtual machine. Please refer to *Note +mixvm::, for a description of these commands, and to *Note Getting +started::, for a tutorial on using the MIX virtual machine. The command +prompt offers command line completion for partially typed commands using +the <TAB> key; e.g., if you type + + lo <TAB> +the command is automatically completed to 'load'. If multiple +completions are available, they will be shown in the echo area. Thus, +typing + + p <TAB> +will produce the following output on the echo area: + + Completions: + pc psym preg pflags pall + pmem +which lists all the available commands starting with 'p'. In addition, +the command prompt maintains a history of typed commands, which can be +recovered using the arrow up and down keys. As mentioned above, a file +containing previous sessions' commands is stored in the configuration +directory '~/.mdk', and reloaded every time you start 'gmixvm'. + + You can change the font used to display the issued commands and the +messages in the echo area using the +'Settings->Change font->Command prompt' and +'Settings->Change font->Command log' menu commands. + + +File: mdk.info, Node: MIX virtual machine, Next: MIXAL source view, Prev: MIXVM console, Up: gmixvm + +7.3 MIX virtual machine +======================= + +The first notebook's page displays the current status of the virtual +machine.

Note that command line options to + mixguile must be written in their own line after the '\' symbol. + + -- User Option: -q + Do not load user's initialisation file. When 'mixguile' starts up, + it looks for a file named 'mixguile.scm' in the user's MDK + configuration directory ('~/.mdk'), and loads it if it exists. + This option tells 'mixguile' to skip this initialisation file + loading. + + +File: mdk.info, Node: Scheme functions reference, Prev: Invoking mixguile, Up: mixguile + +8.2 Scheme functions reference +============================== + +As we have previously pointed out, 'mixguile' embeds a MIX virtual +machine that can be accessed through a set of Scheme functions, that is, +of a Scheme library. Conversely, 'mixvm' and 'gmixvm' contain a Guile +interpreter, and are able to use this same Scheme library, as well as +all the other Guile/Scheme primitives and any user defined function. +Therefore, you have at your disposal a powerful programming language, +Scheme, to extend the MDK virtual machine emulators (see *note Using +Scheme in mixvm and gmixvm:: for samples of how to do it). + + The following subsections describe available functions the MIX/Scheme +library. + +* Menu: + +* mixvm wrappers:: Functions invoking mixvm commands. +* Hooks:: Adding hooks to mixvm commands. +* Additional VM functions:: Functions accessing the MIX virtual machine. + + +File: mdk.info, Node: mixvm wrappers, Next: Hooks, Prev: Scheme functions reference, Up: Scheme functions reference + +8.2.1 'mixvm' command wrappers +------------------------------ + +For each of the 'mixvm' commands listed in *note Commands::, there is a +corresponding Scheme function named by prefixing the command name with +'mix-' (e.g., 'mix-load', 'mix-run' and so on). These command wrappers +are implemented using a generic command dispatching function: + + -- Function: mixvm-cmd command argument + Dispatches the given COMMAND to the MIX virtual machine appending + the provided ARGUMENT. Both COMMAND and 'argument' must be + strings. The net result is as writing "COMMAND ARGUMENT" at the + 'mixvm' or 'gmixvm' command prompt. + + For instance, you can invoke the 'run' command at the 'mixvm' prompt +in three equivalent ways: + + MIX > run hello + MIX > (mix-run "hello") + MIX > (mixvm-cmd "run" "hello") +(only the two last forms can be used at the 'mixguile' prompt or inside +a Scheme script). + + The 'mix-' functions evaluate to a unspecified value. If you want to +check the result of the last 'mixvm' command invocation, use the +'mix-last-result' function: + + -- Function: mix-last-result + Returns #T if the last 'mixvm' command invocation was successful, + #F otherwise. +Using this function, we could improve the script for running a program +presented in the previous section by adding error checking: + + #! /usr/bin/mixguile \ + -e main -s + !# + + ;;; Execute a given program and print the registers. + + (define main + (lambda (args) + ;; load the file provided as a command line argument + (mix-load (cadr args)) + ;; execute it if mix-load succeeded + (if (mix-last-result) (mix-run)) + ;; print the contents of registers if the above commands succeeded + (if (mix-last-result) (mix-pall)))) + + Please, refer to *note Commands:: for a list of available commands. +Given the description of a 'mixvm', it is straightforward to use its +Scheme counterpart and, therefore, we shall not give a complete +description of these functions here. Instead, we will only mention +those wrappers that exhibit a treatment of their differing from that of +their command counterpart. + + -- Function: mix-preg [register] + -- Function: mix-sreg register value + The argument REGISTER of these functions can be either a string or + a symbol representing the desired register. For instance, the + following invocations are equivalent: + + (mix-preg 'I1) + (mix-preg "I1") + + -- Function: mix-pmem from [to] + The command 'pmem' takes a single argument which can be either a + cell number or a range of the form 'FROM-TO'. This function takes + one argument to ask for a single memory cell contents, or two + parameters to ask for a range. For instance, the following + commands are equivalent: + + MIX > pmem 10-12 + 0010: + 00 00 00 00 00 (0000000000) + 0011: + 00 00 00 00 00 (0000000000) + 0012: + 00 00 00 00 00 (0000000000) + MIX > (mix-pmem 10 12) + 0010: + 00 00 00 00 00 (0000000000) + 0011: + 00 00 00 00 00 (0000000000) + 0012: + 00 00 00 00 00 (0000000000) + MIX > + + -- Function: mix-sover #t|#f + The command 'sover' takes as argument either the string 'T' or the + string 'F', to set, respectively, the overflow toggle to true or + false. Its Scheme counterpart, 'mix-sover', takes as argument a + Scheme boolean value: '#t' (true) or '#f'. + + For the remaining functions, you simply must take into account that +when the command arguments are numerical, the corresponding Scheme +function takes as arguments Scheme number literals. On the other hand, +when the command argument is a string, the argument of its associated +Scheme function will be a Scheme string. By way of example, the +following invocations are pairwise equivalent: + + MIX > load ../samples/hello + MIX > (mix-load "../samples/hello") + + MIX > next 5 + MIX > (mix-next 5) + + +File: mdk.info, Node: Hooks, Next: Additional VM functions, Prev: mixvm wrappers, Up: Scheme functions reference + +8.2.2 Hook functions +-------------------- + +Hooks are functions evaluated before or after executing a 'mixvm' +command (or its corresponding Scheme function wrapper), or after an +explicit or conditional breakpoint is found during the execution of a +MIX program. The following functions let you install hooks: + + -- Function: mix-add-pre-hook command hook + Adds a function to the list of pre-hooks associated with the given + COMMAND. COMMAND is a string naming the corresponding 'mixvm' + command, and HOOK is a function which takes a single argument: a + string list of the commands arguments. The following scheme code + defines a simple hook and associates it with the 'run' command: + + (define run-hook + (lambda (args) + (display "argument list: ") + (display args) + (newline))) + (mix-add-pre-hook "run" run-hook) + + Pre-hooks are executed, in the order they are added, before + invoking the corresponding command (or its associated Scheme + wrapper function). + + -- Function: mix-add-post-hook command hook + Adds a function to the list of pre-hooks associated with the given + COMMAND. The arguments have the same meaning as in + 'mix-add-pre-hook'. + + -- Function: mix-add-global-pre-hook hook + -- Function: mix-add-global-post-hook hook + Global pre/post hooks are executed before/after any 'mixvm' command + or function wrapper invocation. In this case, HOOK takes two + arguments: a string with the name of the command being invoked, and + a string list with its arguments. + + -- Function: mix-add-break-hook hook + -- Function: mix-add-cond-break hook + Add a hook funtion to be executed when an explicit (resp. + conditional) breakpoint is encountered during program execution. + HOOK is a function taking two arguments: the source line number + where the hook has occurred, and the current program counter value. + The following code shows a simple definition and installation of a + break hook: + + (define break-hook + (lambda (line address) + (display "Breakpoint at line ") (display line) + (display " and address ") (display address) + (newline))) + (mix-add-break-hook break-hook) + + Break hook functions are entirely implemented in Scheme using + regular post-hooks for the 'next' and 'run' commands. If you are + curious, you can check the Scheme source code at + '_prefix_/share/mdk/mixguile-vm-stat.scm' (where _prefix_ stands + for your root install directory, usually '/usr' or '/usr/local'. + + See *note Hook functions:: for further examples on using hook +functions. + + +File: mdk.info, Node: Additional VM functions, Prev: Hooks, Up: Scheme functions reference + +8.2.3 Additional VM functions +----------------------------- + +When writing non-trivial Scheme extensions using the MIX/Scheme library, +you will probably need to evaluate the contents of the virtual machine +components (registers, memory cells and so on). For instance, you may +need to store the contents of the 'A' register in a variable. The +Scheme functions described so far are of no help: you can print the +contents of 'A' using '(mix-preg 'A)', but you cannot define a variable +containing the contents of 'A'. To address this kind of problems, the +MIX/Scheme library provides the following additional functions: + + -- Function: mixvm-status + -- Function: mix-vm-status + Return the current status of the virtual machine, as a number + ('mixvm-status') or as a symbol ('mix-vm-status'). Possible return + values are: + '(mixvm-status)' '(mix-vm-status)' + 0 MIX_ERROR Loading or execution error + 1 MIX_BREAK Breakpoint encountered + 2 MIX_COND_BREAK Conditional breakpoint + 3 MIX_HALTED Execution terminated + 4 MIX_RUNNING Execution stopped after 'next' + 5 MIX_LOADED Program successfully loaded + 6 MIX_EMPTY No program loaded + + -- Function: mix-vm-error? + -- Function: mix-vm-break? + -- Function: mix-vm-cond-break? + -- Function: mix-vm-halted? + -- Function: mix-vm-running? + -- Function: mix-vm-loaded? + -- Function: mix-vm-empty? + Predicates asking whether the current virtual machine status is + 'MIX_ERROR', 'MIX_BREAK', etc. + + -- Function: mix-reg register + -- Function: mix-set-reg! register value + 'mix-reg' evaluates to a number which is the contents of the + specified REGISTER. 'mix-set-reg' sets the contents of the given + REGISTER to VALUE. The register can be specified either as a + string ('"A"', '"X"', etc.) or as a symbol (''A', ''X', etc.). + For instance, + + guile> (mix-reg 'A) + 2341 + guile> (mix-set-reg! "A" 2000) + ok + guile> (define reg-a (mix-reg 'A)) + guile> (display reg-a) + 2000 + guile> + + -- Function: mix-cell cell_no + -- Function: mix-set-cell! cell_no value + Evaluate and set the contents of the memory cell number CELL_NO. + Both CELL_NO and VALUE are Scheme numbers. + + -- Function: mix-loc + Evaluates to the value of the location counter (i.e., the address + of the next instruction to be executed). + + -- Function: mix-over + -- Function: mix-set-over! #t|#f + 'mix-over' evaluates to '#t' if the overflow toggle is set, and to + '#f' otherwise. The value of the overflow toggle can be modified + using 'mix-set-over!'. + + -- Function: mix-cmp + -- Function: mix-set-cmp! 'L|'E|'G + Evaluate and set the comparison flag. Possible values are the + scheme symbols 'L' (lesser), 'E' (equal) and 'G' (greater). + + -- Function: mix-up-time + Evaluates to the current virtual machine uptime. + + -- Function: mix-lap-time + Evaluates to the current virtual machine lapsed time, i.e., the + time elapsed since the last 'run' or 'next' command. + + -- Function: mix-prog-time + Evaluates to the total time spent executing the currently loaded + program. + + -- Function: mix-prog-name + Evaluates to a string containing the basename (without any leading + path) of the currently loaded MIX program. + + -- Function: mix-prog-path + Evaluates to a string containing the full path to the currently + loaded MIX program. + + -- Function: mix-src-path + Evaluates to a string containing the full path to the source file + of the currently loaded MIX program. + + -- Function: mix-src-line [lineno] + -- Function: mix-src-line-no + 'mix-src-line-no' evaluates to the current source file number + during the execution of a program. 'mix-src-line' evaluates to a + string containing the source file line number LINENO; when invoked + without argument, it evaluates to '(mix-src-line + (mix-src-line-no))'. + + -- Function: mix-ddir + Evaluates to a string containing the full path of the current + device directory. + + +File: mdk.info, Node: Problems, Next: Copying, Prev: mixguile, Up: Top + +9 Reporting Bugs +**************** + +If you have any questions, comments or suggestions, please send +electronic mail to the author <jao@gnu.org>. + + If you find a bug in MDK, please send electronic mail to the MDK bug +list <bug-mdk@gnu.org>. + + In your report, please include the version number, which you can find +by running 'mixasm --version'.

You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +them if you wish), that you receive source code or can get it if you +want it, that you can change the software or use pieces of it in new +free programs, and that you know you can do these things. + + To protect your rights, we need to prevent others from denying you +these rights or asking you to surrender the rights. Therefore, you have +certain responsibilities if you distribute copies of the software, or if +you modify it: responsibilities to respect the freedom of others. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must pass on to the recipients the same +freedoms that you received. You must make sure that they, too, receive +or can get the source code. And you must show them these terms so they +know their rights. + + Developers that use the GNU GPL protect your rights with two steps: +(1) assert copyright on the software, and (2) offer you this License +giving you legal permission to copy, distribute and/or modify it. + + For the developers' and authors' protection, the GPL clearly explains +that there is no warranty for this free software. For both users' and +authors' sake, the GPL requires that modified versions be marked as +changed, so that their problems will not be attributed erroneously to +authors of previous versions. + + Some devices are designed to deny users access to install or run +modified versions of the software inside them, although the manufacturer +can do so. This is fundamentally incompatible with the aim of +protecting users' freedom to change the software. The systematic +pattern of such abuse occurs in the area of products for individuals to +use, which is precisely where it is most unacceptable. Therefore, we +have designed this version of the GPL to prohibit the practice for those +products. If such problems arise substantially in other domains, we +stand ready to extend this provision to those domains in future versions +of the GPL, as needed to protect the freedom of users. + + Finally, every program is threatened constantly by software patents. +States should not allow patents to restrict development and use of +software on general-purpose computers, but in those that do, we wish to +avoid the special danger that patents applied to a free program could +make it effectively proprietary. To prevent this, the GPL assures that +patents cannot be used to render the program non-free. + + The precise terms and conditions for copying, distribution and +modification follow. + +TERMS AND CONDITIONS +==================== + + 0. Definitions. + + "This License" refers to version 3 of the GNU General Public + License. + + "Copyright" also means copyright-like laws that apply to other + kinds of works, such as semiconductor masks. + + "The Program" refers to any copyrightable work licensed under this + License. Each licensee is addressed as "you". "Licensees" and + "recipients" may be individuals or organizations. + + To "modify" a work means to copy from or adapt all or part of the + work in a fashion requiring copyright permission, other than the + making of an exact copy. The resulting work is called a "modified + version" of the earlier work or a work "based on" the earlier work. + + A "covered work" means either the unmodified Program or a work + based on the Program. + + To "propagate" a work means to do anything with it that, without + permission, would make you directly or secondarily liable for + infringement under applicable copyright law, except executing it on + a computer or modifying a private copy. Propagation includes + copying, distribution (with or without modification), making + available to the public, and in some countries other activities as + well. + + To "convey" a work means any kind of propagation that enables other + parties to make or receive copies. Mere interaction with a user + through a computer network, with no transfer of a copy, is not + conveying. + + An interactive user interface displays "Appropriate Legal Notices" + to the extent that it includes a convenient and prominently visible + feature that (1) displays an appropriate copyright notice, and (2) + tells the user that there is no warranty for the work (except to + the extent that warranties are provided), that licensees may convey + the work under this License, and how to view a copy of this + License. If the interface presents a list of user commands or + options, such as a menu, a prominent item in the list meets this + criterion. + + 1. Source Code. + + The "source code" for a work means the preferred form of the work + for making modifications to it. "Object code" means any non-source + form of a work. + + A "Standard Interface" means an interface that either is an + official standard defined by a recognized standards body, or, in + the case of interfaces specified for a particular programming + language, one that is widely used among developers working in that + language. + + The "System Libraries" of an executable work include anything, + other than the work as a whole, that (a) is included in the normal + form of packaging a Major Component, but which is not part of that + Major Component, and (b) serves only to enable use of the work with + that Major Component, or to implement a Standard Interface for + which an implementation is available to the public in source code + form. A "Major Component", in this context, means a major + essential component (kernel, window system, and so on) of the + specific operating system (if any) on which the executable work + runs, or a compiler used to produce the work, or an object code + interpreter used to run it. + + The "Corresponding Source" for a work in object code form means all + the source code needed to generate, install, and (for an executable + work) run the object code and to modify the work, including scripts + to control those activities. However, it does not include the + work's System Libraries, or general-purpose tools or generally + available free programs which are used unmodified in performing + those activities but which are not part of the work. For example, + Corresponding Source includes interface definition files associated + with source files for the work, and the source code for shared + libraries and dynamically linked subprograms that the work is + specifically designed to require, such as by intimate data + communication or control flow between those subprograms and other + parts of the work. + + The Corresponding Source need not include anything that users can + regenerate automatically from other parts of the Corresponding + Source. + + The Corresponding Source for a work in source code form is that + same work. + + 2. Basic Permissions. + + All rights granted under this License are granted for the term of + copyright on the Program, and are irrevocable provided the stated + conditions are met. This License explicitly affirms your unlimited + permission to run the unmodified Program. The output from running + a covered work is covered by this License only if the output, given + its content, constitutes a covered work. This License acknowledges + your rights of fair use or other equivalent, as provided by + copyright law. + + You may make, run and propagate covered works that you do not + convey, without conditions so long as your license otherwise + remains in force. You may convey covered works to others for the + sole purpose of having them make modifications exclusively for you, + or provide you with facilities for running those works, provided + that you comply with the terms of this License in conveying all + material for which you do not control copyright. Those thus making + or running the covered works for you must do so exclusively on your + behalf, under your direction and control, on terms that prohibit + them from making any copies of your copyrighted material outside + their relationship with you. + + Conveying under any other circumstances is permitted solely under + the conditions stated below. Sublicensing is not allowed; section + 10 makes it unnecessary. + + 3. Protecting Users' Legal Rights From Anti-Circumvention Law. + + No covered work shall be deemed part of an effective technological + measure under any applicable law fulfilling obligations under + article 11 of the WIPO copyright treaty adopted on 20 December + 1996, or similar laws prohibiting or restricting circumvention of + such measures. + + When you convey a covered work, you waive any legal power to forbid + circumvention of technological measures to the extent such + circumvention is effected by exercising rights under this License + with respect to the covered work, and you disclaim any intention to + limit operation or modification of the work as a means of + enforcing, against the work's users, your or third parties' legal + rights to forbid circumvention of technological measures. + + 4. Conveying Verbatim Copies. + + You may convey verbatim copies of the Program's source code as you + receive it, in any medium, provided that you conspicuously and + appropriately publish on each copy an appropriate copyright notice; + keep intact all notices stating that this License and any + non-permissive terms added in accord with section 7 apply to the + code; keep intact all notices of the absence of any warranty; and + give all recipients a copy of this License along with the Program. + + You may charge any price or no price for each copy that you convey, + and you may offer support or warranty protection for a fee. + + 5. Conveying Modified Source Versions. + + You may convey a work based on the Program, or the modifications to + produce it from the Program, in the form of source code under the + terms of section 4, provided that you also meet all of these + conditions: + + a. The work must carry prominent notices stating that you + modified it, and giving a relevant date. + + b. The work must carry prominent notices stating that it is + released under this License and any conditions added under + section 7. This requirement modifies the requirement in + section 4 to "keep intact all notices". + + c. You must license the entire work, as a whole, under this + License to anyone who comes into possession of a copy. This + License will therefore apply, along with any applicable + section 7 additional terms, to the whole of the work, and all + its parts, regardless of how they are packaged. This License + gives no permission to license the work in any other way, but + it does not invalidate such permission if you have separately + received it. + + d. If the work has interactive user interfaces, each must display + Appropriate Legal Notices; however, if the Program has + interactive interfaces that do not display Appropriate Legal + Notices, your work need not make them do so. + + A compilation of a covered work with other separate and independent + works, which are not by their nature extensions of the covered + work, and which are not combined with it such as to form a larger + program, in or on a volume of a storage or distribution medium, is + called an "aggregate" if the compilation and its resulting + copyright are not used to limit the access or legal rights of the + compilation's users beyond what the individual works permit. + Inclusion of a covered work in an aggregate does not cause this + License to apply to the other parts of the aggregate. + + 6. Conveying Non-Source Forms. + + You may convey a covered work in object code form under the terms + of sections 4 and 5, provided that you also convey the + machine-readable Corresponding Source under the terms of this + License, in one of these ways: + + a. Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by the + Corresponding Source fixed on a durable physical medium + customarily used for software interchange. + + b. Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by a + written offer, valid for at least three years and valid for as + long as you offer spare parts or customer support for that + product model, to give anyone who possesses the object code + either (1) a copy of the Corresponding Source for all the + software in the product that is covered by this License, on a + durable physical medium customarily used for software + interchange, for a price no more than your reasonable cost of + physically performing this conveying of source, or (2) access + to copy the Corresponding Source from a network server at no + charge. + + c. Convey individual copies of the object code with a copy of the + written offer to provide the Corresponding Source. This + alternative is allowed only occasionally and noncommercially, + and only if you received the object code with such an offer, + in accord with subsection 6b. + + d. Convey the object code by offering access from a designated + place (gratis or for a charge), and offer equivalent access to + the Corresponding Source in the same way through the same + place at no further charge. You need not require recipients + to copy the Corresponding Source along with the object code. + If the place to copy the object code is a network server, the + Corresponding Source may be on a different server (operated by + you or a third party) that supports equivalent copying + facilities, provided you maintain clear directions next to the + object code saying where to find the Corresponding Source. + Regardless of what server hosts the Corresponding Source, you + remain obligated to ensure that it is available for as long as + needed to satisfy these requirements. + + e. Convey the object code using peer-to-peer transmission, + provided you inform other peers where the object code and + Corresponding Source of the work are being offered to the + general public at no charge under subsection 6d. + + A separable portion of the object code, whose source code is + excluded from the Corresponding Source as a System Library, need + not be included in conveying the object code work. + + A "User Product" is either (1) a "consumer product", which means + any tangible personal property which is normally used for personal, + family, or household purposes, or (2) anything designed or sold for + incorporation into a dwelling. In determining whether a product is + a consumer product, doubtful cases shall be resolved in favor of + coverage. For a particular product received by a particular user, + "normally used" refers to a typical or common use of that class of + product, regardless of the status of the particular user or of the + way in which the particular user actually uses, or expects or is + expected to use, the product. A product is a consumer product + regardless of whether the product has substantial commercial, + industrial or non-consumer uses, unless such uses represent the + only significant mode of use of the product. + + "Installation Information" for a User Product means any methods, + procedures, authorization keys, or other information required to + install and execute modified versions of a covered work in that + User Product from a modified version of its Corresponding Source. + The information must suffice to ensure that the continued + functioning of the modified object code is in no case prevented or + interfered with solely because modification has been made. + + If you convey an object code work under this section in, or with, + or specifically for use in, a User Product, and the conveying + occurs as part of a transaction in which the right of possession + and use of the User Product is transferred to the recipient in + perpetuity or for a fixed term (regardless of how the transaction + is characterized), the Corresponding Source conveyed under this + section must be accompanied by the Installation Information. But + this requirement does not apply if neither you nor any third party + retains the ability to install modified object code on the User + Product (for example, the work has been installed in ROM). + + The requirement to provide Installation Information does not + include a requirement to continue to provide support service, + warranty, or updates for a work that has been modified or installed + by the recipient, or for the User Product in which it has been + modified or installed. Access to a network may be denied when the + modification itself materially and adversely affects the operation + of the network or violates the rules and protocols for + communication across the network. + + Corresponding Source conveyed, and Installation Information + provided, in accord with this section must be in a format that is + publicly documented (and with an implementation available to the + public in source code form), and must require no special password + or key for unpacking, reading or copying. + + 7. Additional Terms. + + "Additional permissions" are terms that supplement the terms of + this License by making exceptions from one or more of its + conditions. Additional permissions that are applicable to the + entire Program shall be treated as though they were included in + this License, to the extent that they are valid under applicable + law. If additional permissions apply only to part of the Program, + that part may be used separately under those permissions, but the + entire Program remains governed by this License without regard to + the additional permissions. + + When you convey a copy of a covered work, you may at your option + remove any additional permissions from that copy, or from any part + of it. (Additional permissions may be written to require their own + removal in certain cases when you modify the work.) You may place + additional permissions on material, added by you to a covered work, + for which you have or can give appropriate copyright permission. + + Notwithstanding any other provision of this License, for material + you add to a covered work, you may (if authorized by the copyright + holders of that material) supplement the terms of this License with + terms: + + a. Disclaiming warranty or limiting liability differently from + the terms of sections 15 and 16 of this License; or + + b. Requiring preservation of specified reasonable legal notices + or author attributions in that material or in the Appropriate + Legal Notices displayed by works containing it; or + + c. Prohibiting misrepresentation of the origin of that material, + or requiring that modified versions of such material be marked + in reasonable ways as different from the original version; or + + d. Limiting the use for publicity purposes of names of licensors + or authors of the material; or + + e. Declining to grant rights under trademark law for use of some + trade names, trademarks, or service marks; or + + f. Requiring indemnification of licensors and authors of that + material by anyone who conveys the material (or modified + versions of it) with contractual assumptions of liability to + the recipient, for any liability that these contractual + assumptions directly impose on those licensors and authors. + + All other non-permissive additional terms are considered "further + restrictions" within the meaning of section 10. If the Program as + you received it, or any part of it, contains a notice stating that + it is governed by this License along with a term that is a further + restriction, you may remove that term. If a license document + contains a further restriction but permits relicensing or conveying + under this License, you may add to a covered work material governed + by the terms of that license document, provided that the further + restriction does not survive such relicensing or conveying. + + If you add terms to a covered work in accord with this section, you + must place, in the relevant source files, a statement of the + additional terms that apply to those files, or a notice indicating + where to find the applicable terms. + + Additional terms, permissive or non-permissive, may be stated in + the form of a separately written license, or stated as exceptions; + the above requirements apply either way. + + 8. Termination. + + You may not propagate or modify a covered work except as expressly + provided under this License. Any attempt otherwise to propagate or + modify it is void, and will automatically terminate your rights + under this License (including any patent licenses granted under the + third paragraph of section 11). + + However, if you cease all violation of this License, then your + license from a particular copyright holder is reinstated (a) + provisionally, unless and until the copyright holder explicitly and + finally terminates your license, and (b) permanently, if the + copyright holder fails to notify you of the violation by some + reasonable means prior to 60 days after the cessation. + + Moreover, your license from a particular copyright holder is + reinstated permanently if the copyright holder notifies you of the + violation by some reasonable means, this is the first time you have + received notice of violation of this License (for any work) from + that copyright holder, and you cure the violation prior to 30 days + after your receipt of the notice. + + Termination of your rights under this section does not terminate + the licenses of parties who have received copies or rights from you + under this License. If your rights have been terminated and not + permanently reinstated, you do not qualify to receive new licenses + for the same material under section 10. + + 9. Acceptance Not Required for Having Copies. + + You are not required to accept this License in order to receive or + run a copy of the Program. Ancillary propagation of a covered work + occurring solely as a consequence of using peer-to-peer + transmission to receive a copy likewise does not require + acceptance. However, nothing other than this License grants you + permission to propagate or modify any covered work. These actions + infringe copyright if you do not accept this License. Therefore, + by modifying or propagating a covered work, you indicate your + acceptance of this License to do so. + + 10. Automatic Licensing of Downstream Recipients. + + Each time you convey a covered work, the recipient automatically + receives a license from the original licensors, to run, modify and + propagate that work, subject to this License. You are not + responsible for enforcing compliance by third parties with this + License. + + An "entity transaction" is a transaction transferring control of an + organization, or substantially all assets of one, or subdividing an + organization, or merging organizations. If propagation of a + covered work results from an entity transaction, each party to that + transaction who receives a copy of the work also receives whatever + licenses to the work the party's predecessor in interest had or + could give under the previous paragraph, plus a right to possession + of the Corresponding Source of the work from the predecessor in + interest, if the predecessor has it or can get it with reasonable + efforts. + + You may not impose any further restrictions on the exercise of the + rights granted or affirmed under this License. For example, you + may not impose a license fee, royalty, or other charge for exercise + of rights granted under this License, and you may not initiate + litigation (including a cross-claim or counterclaim in a lawsuit) + alleging that any patent claim is infringed by making, using, + selling, offering for sale, or importing the Program or any portion + of it. + + 11. Patents. + + A "contributor" is a copyright holder who authorizes use under this + License of the Program or a work on which the Program is based. + The work thus licensed is called the contributor's "contributor + version". + + A contributor's "essential patent claims" are all patent claims + owned or controlled by the contributor, whether already acquired or + hereafter acquired, that would be infringed by some manner, + permitted by this License, of making, using, or selling its + contributor version, but do not include claims that would be + infringed only as a consequence of further modification of the + contributor version. For purposes of this definition, "control" + includes the right to grant patent sublicenses in a manner + consistent with the requirements of this License. + + Each contributor grants you a non-exclusive, worldwide, + royalty-free patent license under the contributor's essential + patent claims, to make, use, sell, offer for sale, import and + otherwise run, modify and propagate the contents of its contributor + version. + + In the following three paragraphs, a "patent license" is any + express agreement or commitment, however denominated, not to + enforce a patent (such as an express permission to practice a + patent or covenant not to sue for patent infringement). To "grant" + such a patent license to a party means to make such an agreement or + commitment not to enforce a patent against the party. + + If you convey a covered work, knowingly relying on a patent + license, and the Corresponding Source of the work is not available + for anyone to copy, free of charge and under the terms of this + License, through a publicly available network server or other + readily accessible means, then you must either (1) cause the + Corresponding Source to be so available, or (2) arrange to deprive + yourself of the benefit of the patent license for this particular + work, or (3) arrange, in a manner consistent with the requirements + of this License, to extend the patent license to downstream + recipients. "Knowingly relying" means you have actual knowledge + that, but for the patent license, your conveying the covered work + in a country, or your recipient's use of the covered work in a + country, would infringe one or more identifiable patents in that + country that you have reason to believe are valid. + + If, pursuant to or in connection with a single transaction or + arrangement, you convey, or propagate by procuring conveyance of, a + covered work, and grant a patent license to some of the parties + receiving the covered work authorizing them to use, propagate, + modify or convey a specific copy of the covered work, then the + patent license you grant is automatically extended to all + recipients of the covered work and works based on it. + + A patent license is "discriminatory" if it does not include within + the scope of its coverage, prohibits the exercise of, or is + conditioned on the non-exercise of one or more of the rights that + are specifically granted under this License. You may not convey a + covered work if you are a party to an arrangement with a third + party that is in the business of distributing software, under which + you make payment to the third party based on the extent of your + activity of conveying the work, and under which the third party + grants, to any of the parties who would receive the covered work + from you, a discriminatory patent license (a) in connection with + copies of the covered work conveyed by you (or copies made from + those copies), or (b) primarily for and in connection with specific + products or compilations that contain the covered work, unless you + entered into that arrangement, or that patent license was granted, + prior to 28 March 2007. + + Nothing in this License shall be construed as excluding or limiting + any implied license or other defenses to infringement that may + otherwise be available to you under applicable patent law. + + 12. No Surrender of Others' Freedom. + + If conditions are imposed on you (whether by court order, agreement + or otherwise) that contradict the conditions of this License, they + do not excuse you from the conditions of this License. If you + cannot convey a covered work so as to satisfy simultaneously your + obligations under this License and any other pertinent obligations, + then as a consequence you may not convey it at all. For example, + if you agree to terms that obligate you to collect a royalty for + further conveying from those to whom you convey the Program, the + only way you could satisfy both those terms and this License would + be to refrain entirely from conveying the Program. + + 13. Use with the GNU Affero General Public License. + + Notwithstanding any other provision of this License, you have + permission to link or combine any covered work with a work licensed + under version 3 of the GNU Affero General Public License into a + single combined work, and to convey the resulting work. The terms + of this License will continue to apply to the part which is the + covered work, but the special requirements of the GNU Affero + General Public License, section 13, concerning interaction through + a network will apply to the combination as such. + + 14. Revised Versions of this License. + + The Free Software Foundation may publish revised and/or new + versions of the GNU General Public License from time to time. Such + new versions will be similar in spirit to the present version, but + may differ in detail to address new problems or concerns. + + Each version is given a distinguishing version number. If the + Program specifies that a certain numbered version of the GNU + General Public License "or any later version" applies to it, you + have the option of following the terms and conditions either of + that numbered version or of any later version published by the Free + Software Foundation. If the Program does not specify a version + number of the GNU General Public License, you may choose any + version ever published by the Free Software Foundation. + + If the Program specifies that a proxy can decide which future + versions of the GNU General Public License can be used, that + proxy's public statement of acceptance of a version permanently + authorizes you to choose that version for the Program. + + Later license versions may give you additional or different + permissions. However, no additional obligations are imposed on any + author or copyright holder as a result of your choosing to follow a + later version. + + 15. Disclaimer of Warranty. + + THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY + APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE + COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" + WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, + INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF + MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE + RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. + SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL + NECESSARY SERVICING, REPAIR OR CORRECTION. + + 16. Limitation of Liability. + + IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN + WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES + AND/OR CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR + DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR + CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE + THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA + BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD + PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER + PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF + THE POSSIBILITY OF SUCH DAMAGES. + + 17. Interpretation of Sections 15 and 16. + + If the disclaimer of warranty and limitation of liability provided + above cannot be given local legal effect according to their terms, + reviewing courts shall apply local law that most closely + approximates an absolute waiver of all civil liability in + connection with the Program, unless a warranty or assumption of + liability accompanies a copy of the Program in return for a fee. + +END OF TERMS AND CONDITIONS +=========================== + +How to Apply These Terms to Your New Programs +============================================= + +If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these +terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +state the exclusion of warranty; and each file should have at least the +"copyright" line and a pointer to where the full notice is found. + + ONE LINE TO GIVE THE PROGRAM'S NAME AND A BRIEF IDEA OF WHAT IT DOES. + Copyright (C) YEAR NAME OF AUTHOR + + This program is free software: you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation, either version 3 of the License, or (at + your option) any later version. + + This program is distributed in the hope that it will be useful, but + WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU + General Public License for more details. + + You should have received a copy of the GNU General Public License + along with this program. If not, see <http://www.gnu.org/licenses/>. + + Also add information on how to contact you by electronic and paper +mail. + + If the program does terminal interaction, make it output a short +notice like this when it starts in an interactive mode: + + PROGRAM Copyright (C) YEAR NAME OF AUTHOR + This program comes with ABSOLUTELY NO WARRANTY; for details type 'show w'. + This is free software, and you are welcome to redistribute it + under certain conditions; type 'show c' for details. + + The hypothetical commands 'show w' and 'show c' should show the +appropriate parts of the General Public License. Of course, your +program's commands might be different; for a GUI interface, you would +use an "about box". + + You should also get your employer (if you work as a programmer) or +school, if any, to sign a "copyright disclaimer" for the program, if +necessary. For more information on this, and how to apply and follow +the GNU GPL, see <http://www.gnu.org/licenses/>. + + The GNU General Public License does not permit incorporating your +program into proprietary programs. If your program is a subroutine +library, you may consider it more useful to permit linking proprietary +applications with the library. If this is what you want to do, use the +GNU Lesser General Public License instead of this License. But first, +please read <http://www.gnu.org/philosophy/why-not-lgpl.html>. + + +File: mdk.info, Node: GNU Free Documentation License, Prev: GNU General Public License, Up: Copying + +A.2 GNU Free Documentation License +================================== + + Version 1.2, November 2002 + + Copyright (C) 2000,2001,2002 Free Software Foundation, Inc. + 51 Franklin St, Fifth Floor, Boston, MA 02110-1301, USA + + Everyone is permitted to copy and distribute verbatim copies + of this license document, but changing it is not allowed. + + 0. PREAMBLE + + The purpose of this License is to make a manual, textbook, or other + functional and useful document "free" in the sense of freedom: to + assure everyone the effective freedom to copy and redistribute it, + with or without modifying it, either commercially or + noncommercially. Secondarily, this License preserves for the + author and publisher a way to get credit for their work, while not + being considered responsible for modifications made by others. + + This License is a kind of "copyleft", which means that derivative + works of the document must themselves be free in the same sense. + It complements the GNU General Public License, which is a copyleft + license designed for free software. + + We have designed this License in order to use it for manuals for + free software, because free software needs free documentation: a + free program should come with manuals providing the same freedoms + that the software does. But this License is not limited to + software manuals; it can be used for any textual work, regardless + of subject matter or whether it is published as a printed book. We + recommend this License principally for works whose purpose is + instruction or reference. + + 1. APPLICABILITY AND DEFINITIONS + + This License applies to any manual or other work, in any medium, + that contains a notice placed by the copyright holder saying it can + be distributed under the terms of this License. Such a notice + grants a world-wide, royalty-free license, unlimited in duration, + to use that work under the conditions stated herein. The + "Document", below, refers to any such manual or work. Any member + of the public is a licensee, and is addressed as "you". You accept + the license if you copy, modify or distribute the work in a way + requiring permission under copyright law. + + A "Modified Version" of the Document means any work containing the + Document or a portion of it, either copied verbatim, or with + modifications and/or translated into another language. + + A "Secondary Section" is a named appendix or a front-matter section + of the Document that deals exclusively with the relationship of the + publishers or authors of the Document to the Document's overall + subject (or to related matters) and contains nothing that could + fall directly within that overall subject. (Thus, if the Document + is in part a textbook of mathematics, a Secondary Section may not + explain any mathematics.) The relationship could be a matter of + historical connection with the subject or with related matters, or + of legal, commercial, philosophical, ethical or political position + regarding them. + + The "Invariant Sections" are certain Secondary Sections whose + titles are designated, as being those of Invariant Sections, in the + notice that says that the Document is released under this License. + If a section does not fit the above definition of Secondary then it + is not allowed to be designated as Invariant. The Document may + contain zero Invariant Sections. If the Document does not identify + any Invariant Sections then there are none. + + The "Cover Texts" are certain short passages of text that are + listed, as Front-Cover Texts or Back-Cover Texts, in the notice + that says that the Document is released under this License. A + Front-Cover Text may be at most 5 words, and a Back-Cover Text may + be at most 25 words. + + A "Transparent" copy of the Document means a machine-readable copy, + represented in a format whose specification is available to the + general public, that is suitable for revising the document + straightforwardly with generic text editors or (for images composed + of pixels) generic paint programs or (for drawings) some widely + available drawing editor, and that is suitable for input to text + formatters or for automatic translation to a variety of formats + suitable for input to text formatters. A copy made in an otherwise + Transparent file format whose markup, or absence of markup, has + been arranged to thwart or discourage subsequent modification by + readers is not Transparent. An image format is not Transparent if + used for any substantial amount of text. A copy that is not + "Transparent" is called "Opaque". + + Examples of suitable formats for Transparent copies include plain + ASCII without markup, Texinfo input format, LaTeX input format, + SGML or XML using a publicly available DTD, and standard-conforming + simple HTML, PostScript or PDF designed for human modification. + Examples of transparent image formats include PNG, XCF and JPG. + Opaque formats include proprietary formats that can be read and + edited only by proprietary word processors, SGML or XML for which + the DTD and/or processing tools are not generally available, and + the machine-generated HTML, PostScript or PDF produced by some word + processors for output purposes only. + + The "Title Page" means, for a printed book, the title page itself, + plus such following pages as are needed to hold, legibly, the + material this License requires to appear in the title page. For + works in formats which do not have any title page as such, "Title + Page" means the text near the most prominent appearance of the + work's title, preceding the beginning of the body of the text. + + A section "Entitled XYZ" means a named subunit of the Document + whose title either is precisely XYZ or contains XYZ in parentheses + following text that translates XYZ in another language. (Here XYZ + stands for a specific section name mentioned below, such as + "Acknowledgements", "Dedications", "Endorsements", or "History".) + To "Preserve the Title" of such a section when you modify the + Document means that it remains a section "Entitled XYZ" according + to this definition. + + The Document may include Warranty Disclaimers next to the notice + which states that this License applies to the Document. These + Warranty Disclaimers are considered to be included by reference in + this License, but only as regards disclaiming warranties: any other + implication that these Warranty Disclaimers may have is void and + has no effect on the meaning of this License. + + 2. VERBATIM COPYING + + You may copy and distribute the Document in any medium, either + commercially or noncommercially, provided that this License, the + copyright notices, and the license notice saying this License + applies to the Document are reproduced in all copies, and that you + add no other conditions whatsoever to those of this License. You + may not use technical measures to obstruct or control the reading + or further copying of the copies you make or distribute. However, + you may accept compensation in exchange for copies. If you + distribute a large enough number of copies you must also follow the + conditions in section 3. + + You may also lend copies, under the same conditions stated above, + and you may publicly display copies. + + 3. COPYING IN QUANTITY + + If you publish printed copies (or copies in media that commonly + have printed covers) of the Document, numbering more than 100, and + the Document's license notice requires Cover Texts, you must + enclose the copies in covers that carry, clearly and legibly, all + these Cover Texts: Front-Cover Texts on the front cover, and + Back-Cover Texts on the back cover. Both covers must also clearly + and legibly identify you as the publisher of these copies. The + front cover must present the full title with all words of the title + equally prominent and visible. You may add other material on the + covers in addition. Copying with changes limited to the covers, as + long as they preserve the title of the Document and satisfy these + conditions, can be treated as verbatim copying in other respects. + + If the required texts for either cover are too voluminous to fit + legibly, you should put the first ones listed (as many as fit + reasonably) on the actual cover, and continue the rest onto + adjacent pages. + + If you publish or distribute Opaque copies of the Document + numbering more than 100, you must either include a machine-readable + Transparent copy along with each Opaque copy, or state in or with + each Opaque copy a computer-network location from which the general + network-using public has access to download using public-standard + network protocols a complete Transparent copy of the Document, free + of added material. If you use the latter option, you must take + reasonably prudent steps, when you begin distribution of Opaque + copies in quantity, to ensure that this Transparent copy will + remain thus accessible at the stated location until at least one + year after the last time you distribute an Opaque copy (directly or + through your agents or retailers) of that edition to the public. + + It is requested, but not required, that you contact the authors of + the Document well before redistributing any large number of copies, + to give them a chance to provide you with an updated version of the + Document. + + 4. MODIFICATIONS + + You may copy and distribute a Modified Version of the Document + under the conditions of sections 2 and 3 above, provided that you + release the Modified Version under precisely this License, with the + Modified Version filling the role of the Document, thus licensing + distribution and modification of the Modified Version to whoever + possesses a copy of it. In addition, you must do these things in + the Modified Version: + + A. Use in the Title Page (and on the covers, if any) a title + distinct from that of the Document, and from those of previous + versions (which should, if there were any, be listed in the + History section of the Document). You may use the same title + as a previous version if the original publisher of that + version gives permission. + + B. List on the Title Page, as authors, one or more persons or + entities responsible for authorship of the modifications in + the Modified Version, together with at least five of the + principal authors of the Document (all of its principal + authors, if it has fewer than five), unless they release you + from this requirement. + + C. State on the Title page the name of the publisher of the + Modified Version, as the publisher. + + D. Preserve all the copyright notices of the Document. + + E. Add an appropriate copyright notice for your modifications + adjacent to the other copyright notices. + + F. Include, immediately after the copyright notices, a license + notice giving the public permission to use the Modified + Version under the terms of this License, in the form shown in + the Addendum below. + + G. Preserve in that license notice the full lists of Invariant + Sections and required Cover Texts given in the Document's + license notice. + + H. Include an unaltered copy of this License. + + I. Preserve the section Entitled "History", Preserve its Title, + and add to it an item stating at least the title, year, new + authors, and publisher of the Modified Version as given on the + Title Page. If there is no section Entitled "History" in the + Document, create one stating the title, year, authors, and + publisher of the Document as given on its Title Page, then add + an item describing the Modified Version as stated in the + previous sentence. + + J. Preserve the network location, if any, given in the Document + for public access to a Transparent copy of the Document, and + likewise the network locations given in the Document for + previous versions it was based on. These may be placed in the + "History" section. You may omit a network location for a work + that was published at least four years before the Document + itself, or if the original publisher of the version it refers + to gives permission. + + K. For any section Entitled "Acknowledgements" or "Dedications", + Preserve the Title of the section, and preserve in the section + all the substance and tone of each of the contributor + acknowledgements and/or dedications given therein. + + L. Preserve all the Invariant Sections of the Document, unaltered + in their text and in their titles. Section numbers or the + equivalent are not considered part of the section titles. + + M. Delete any section Entitled "Endorsements". Such a section + may not be included in the Modified Version. + + N. Do not retitle any existing section to be Entitled + "Endorsements" or to conflict in title with any Invariant + Section. + + O. Preserve any Warranty Disclaimers. + + If the Modified Version includes new front-matter sections or + appendices that qualify as Secondary Sections and contain no + material copied from the Document, you may at your option designate + some or all of these sections as invariant. To do this, add their + titles to the list of Invariant Sections in the Modified Version's + license notice. These titles must be distinct from any other + section titles. + + You may add a section Entitled "Endorsements", provided it contains + nothing but endorsements of your Modified Version by various + parties--for example, statements of peer review or that the text + has been approved by an organization as the authoritative + definition of a standard. + + You may add a passage of up to five words as a Front-Cover Text, + and a passage of up to 25 words as a Back-Cover Text, to the end of + the list of Cover Texts in the Modified Version. Only one passage + of Front-Cover Text and one of Back-Cover Text may be added by (or + through arrangements made by) any one entity. If the Document + already includes a cover text for the same cover, previously added + by you or by arrangement made by the same entity you are acting on + behalf of, you may not add another; but you may replace the old + one, on explicit permission from the previous publisher that added + the old one. + + The author(s) and publisher(s) of the Document do not by this + License give permission to use their names for publicity for or to + assert or imply endorsement of any Modified Version. + + 5. COMBINING DOCUMENTS + + You may combine the Document with other documents released under + this License, under the terms defined in section 4 above for + modified versions, provided that you include in the combination all + of the Invariant Sections of all of the original documents, + unmodified, and list them all as Invariant Sections of your + combined work in its license notice, and that you preserve all + their Warranty Disclaimers. + + The combined work need only contain one copy of this License, and + multiple identical Invariant Sections may be replaced with a single + copy. If there are multiple Invariant Sections with the same name + but different contents, make the title of each such section unique + by adding at the end of it, in parentheses, the name of the + original author or publisher of that section if known, or else a + unique number. Make the same adjustment to the section titles in + the list of Invariant Sections in the license notice of the + combined work. + + In the combination, you must combine any sections Entitled + "History" in the various original documents, forming one section + Entitled "History"; likewise combine any sections Entitled + "Acknowledgements", and any sections Entitled "Dedications". You + must delete all sections Entitled "Endorsements." + + 6. COLLECTIONS OF DOCUMENTS + + You may make a collection consisting of the Document and other + documents released under this License, and replace the individual + copies of this License in the various documents with a single copy + that is included in the collection, provided that you follow the + rules of this License for verbatim copying of each of the documents + in all other respects. + + You may extract a single document from such a collection, and + distribute it individually under this License, provided you insert + a copy of this License into the extracted document, and follow this + License in all other respects regarding verbatim copying of that + document. + + 7. AGGREGATION WITH INDEPENDENT WORKS + + A compilation of the Document or its derivatives with other + separate and independent documents or works, in or on a volume of a + storage or distribution medium, is called an "aggregate" if the + copyright resulting from the compilation is not used to limit the + legal rights of the compilation's users beyond what the individual + works permit. When the Document is included in an aggregate, this + License does not apply to the other works in the aggregate which + are not themselves derivative works of the Document. + + If the Cover Text requirement of section 3 is applicable to these + copies of the Document, then if the Document is less than one half + of the entire aggregate, the Document's Cover Texts may be placed + on covers that bracket the Document within the aggregate, or the + electronic equivalent of covers if the Document is in electronic + form. Otherwise they must appear on printed covers that bracket + the whole aggregate. + + 8. TRANSLATION + + Translation is considered a kind of modification, so you may + distribute translations of the Document under the terms of section + 4. Replacing Invariant Sections with translations requires special + permission from their copyright holders, but you may include + translations of some or all Invariant Sections in addition to the + original versions of these Invariant Sections. You may include a + translation of this License, and all the license notices in the + Document, and any Warranty Disclaimers, provided that you also + include the original English version of this License and the + original versions of those notices and disclaimers. In case of a + disagreement between the translation and the original version of + this License or a notice or disclaimer, the original version will + prevail. + + If a section in the Document is Entitled "Acknowledgements", + "Dedications", or "History", the requirement (section 4) to + Preserve its Title (section 1) will typically require changing the + actual title. + + 9. TERMINATION + + You may not copy, modify, sublicense, or distribute the Document + except as expressly provided for under this License. Any other + attempt to copy, modify, sublicense or distribute the Document is + void, and will automatically terminate your rights under this + License. However, parties who have received copies, or rights, + from you under this License will not have their licenses terminated + so long as such parties remain in full compliance. + + 10. FUTURE REVISIONS OF THIS LICENSE + + The Free Software Foundation may publish new, revised versions of + the GNU Free Documentation License from time to time. Such new + versions will be similar in spirit to the present version, but may + differ in detail to address new problems or concerns. See + <http://www.gnu.org/copyleft/>. + + Each version of the License is given a distinguishing version + number. If the Document specifies that a particular numbered + version of this License "or any later version" applies to it, you + have the option of following the terms and conditions either of + that specified version or of any later version that has been + published (not as a draft) by the Free Software Foundation. If the + Document does not specify a version number of this License, you may + choose any version ever published (not as a draft) by the Free + Software Foundation. + +ADDENDUM: How to use this License for your documents +==================================================== + +To use this License in a document you have written, include a copy of +the License in the document and put the following copyright and license +notices just after the title page: + + Copyright (C) YEAR YOUR NAME. + Permission is granted to copy, distribute and/or modify this document + under the terms of the GNU Free Documentation License, Version 1.2 + or any later version published by the Free Software Foundation; + with no Invariant Sections, no Front-Cover Texts, and no Back-Cover + Texts. A copy of the license is included in the section entitled ``GNU + Free Documentation License''. + + If you have Invariant Sections, Front-Cover Texts and Back-Cover +Texts, replace the "with...Texts." line with this: + + with the Invariant Sections being LIST THEIR TITLES, with + the Front-Cover Texts being LIST, and with the Back-Cover Texts + being LIST. + + If you have Invariant Sections without Cover Texts, or some other +combination of the three, merge those two alternatives to suit the +situation. + + If your document contains nontrivial examples of program code, we +recommend releasing these examples in parallel under your choice of free +software license, such as the GNU General Public License, to permit +their use in free software. + + +File: mdk.info, Node: Concept Index, Next: Instructions and commands, Prev: Copying, Up: Top + +Concept Index +************* + + +* Menu: + +* .mix file: Compiling.

By contrast, +the GNU General Public License is intended to guarantee your freedom +to share and change all versions of a program---to make sure it remains +free software for all its users. We, the Free Software Foundation, +use the GNU General Public License for most of our software; it +applies also to any other work released this way by its authors. You +can apply it to your programs, too. + +When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +them if you wish), that you receive source code or can get it if you +want it, that you can change the software or use pieces of it in new +free programs, and that you know you can do these things. + +To protect your rights, we need to prevent others from denying you +these rights or asking you to surrender the rights. Therefore, you +have certain responsibilities if you distribute copies of the +software, or if you modify it: responsibilities to respect the freedom +of others. + +For example, if you distribute copies of such a program, whether +gratis or for a fee, you must pass on to the recipients the same +freedoms that you received. You must make sure that they, too, +receive or can get the source code. And you must show them these +terms so they know their rights. + +Developers that use the GNU GPL protect your rights with two steps: +(1) assert copyright on the software, and (2) offer you this License +giving you legal permission to copy, distribute and/or modify it. + +For the developers' and authors' protection, the GPL clearly explains +that there is no warranty for this free software. For both users' and +authors' sake, the GPL requires that modified versions be marked as +changed, so that their problems will not be attributed erroneously to +authors of previous versions. + +Some devices are designed to deny users access to install or run +modified versions of the software inside them, although the +manufacturer can do so. This is fundamentally incompatible with the +aim of protecting users' freedom to change the software. The +systematic pattern of such abuse occurs in the area of products for +individuals to use, which is precisely where it is most unacceptable. +Therefore, we have designed this version of the GPL to prohibit the +practice for those products. If such problems arise substantially in +other domains, we stand ready to extend this provision to those +domains in future versions of the GPL, as needed to protect the +freedom of users. + +Finally, every program is threatened constantly by software patents. +States should not allow patents to restrict development and use of +software on general-purpose computers, but in those that do, we wish +to avoid the special danger that patents applied to a free program +could make it effectively proprietary. To prevent this, the GPL +assures that patents cannot be used to render the program non-free. + +The precise terms and conditions for copying, distribution and +modification follow. + +@heading TERMS AND CONDITIONS + +@enumerate 0 +@item Definitions. + +``This License'' refers to version 3 of the GNU General Public License. + +``Copyright'' also means copyright-like laws that apply to other kinds +of works, such as semiconductor masks. + +``The Program'' refers to any copyrightable work licensed under this +License. Each licensee is addressed as ``you''. ``Licensees'' and +``recipients'' may be individuals or organizations. + +To ``modify'' a work means to copy from or adapt all or part of the work +in a fashion requiring copyright permission, other than the making of +an exact copy. The resulting work is called a ``modified version'' of +the earlier work or a work ``based on'' the earlier work. + +A ``covered work'' means either the unmodified Program or a work based +on the Program. + +To ``propagate'' a work means to do anything with it that, without +permission, would make you directly or secondarily liable for +infringement under applicable copyright law, except executing it on a +computer or modifying a private copy. Propagation includes copying, +distribution (with or without modification), making available to the +public, and in some countries other activities as well. + +To ``convey'' a work means any kind of propagation that enables other +parties to make or receive copies. Mere interaction with a user +through a computer network, with no transfer of a copy, is not +conveying. + +An interactive user interface displays ``Appropriate Legal Notices'' to +the extent that it includes a convenient and prominently visible +feature that (1) displays an appropriate copyright notice, and (2) +tells the user that there is no warranty for the work (except to the +extent that warranties are provided), that licensees may convey the +work under this License, and how to view a copy of this License. If +the interface presents a list of user commands or options, such as a +menu, a prominent item in the list meets this criterion. + +@item Source Code. + +The ``source code'' for a work means the preferred form of the work for +making modifications to it. ``Object code'' means any non-source form +of a work. + +A ``Standard Interface'' means an interface that either is an official +standard defined by a recognized standards body, or, in the case of +interfaces specified for a particular programming language, one that +is widely used among developers working in that language. + +The ``System Libraries'' of an executable work include anything, other +than the work as a whole, that (a) is included in the normal form of +packaging a Major Component, but which is not part of that Major +Component, and (b) serves only to enable use of the work with that +Major Component, or to implement a Standard Interface for which an +implementation is available to the public in source code form. A +``Major Component'', in this context, means a major essential component +(kernel, window system, and so on) of the specific operating system +(if any) on which the executable work runs, or a compiler used to +produce the work, or an object code interpreter used to run it. + +The ``Corresponding Source'' for a work in object code form means all +the source code needed to generate, install, and (for an executable +work) run the object code and to modify the work, including scripts to +control those activities. However, it does not include the work's +System Libraries, or general-purpose tools or generally available free +programs which are used unmodified in performing those activities but +which are not part of the work. For example, Corresponding Source +includes interface definition files associated with source files for +the work, and the source code for shared libraries and dynamically +linked subprograms that the work is specifically designed to require, +such as by intimate data communication or control flow between those +subprograms and other parts of the work. + +The Corresponding Source need not include anything that users can +regenerate automatically from other parts of the Corresponding Source. + +The Corresponding Source for a work in source code form is that same +work. + +@item Basic Permissions. + +All rights granted under this License are granted for the term of +copyright on the Program, and are irrevocable provided the stated +conditions are met. This License explicitly affirms your unlimited +permission to run the unmodified Program. The output from running a +covered work is covered by this License only if the output, given its +content, constitutes a covered work. This License acknowledges your +rights of fair use or other equivalent, as provided by copyright law. + +You may make, run and propagate covered works that you do not convey, +without conditions so long as your license otherwise remains in force. +You may convey covered works to others for the sole purpose of having +them make modifications exclusively for you, or provide you with +facilities for running those works, provided that you comply with the +terms of this License in conveying all material for which you do not +control copyright. Those thus making or running the covered works for +you must do so exclusively on your behalf, under your direction and +control, on terms that prohibit them from making any copies of your +copyrighted material outside their relationship with you. + +Conveying under any other circumstances is permitted solely under the +conditions stated below. Sublicensing is not allowed; section 10 +makes it unnecessary. + +@item Protecting Users' Legal Rights From Anti-Circumvention Law. + +No covered work shall be deemed part of an effective technological +measure under any applicable law fulfilling obligations under article +11 of the WIPO copyright treaty adopted on 20 December 1996, or +similar laws prohibiting or restricting circumvention of such +measures. + +When you convey a covered work, you waive any legal power to forbid +circumvention of technological measures to the extent such +circumvention is effected by exercising rights under this License with +respect to the covered work, and you disclaim any intention to limit +operation or modification of the work as a means of enforcing, against +the work's users, your or third parties' legal rights to forbid +circumvention of technological measures. + +@item Conveying Verbatim Copies. + +You may convey verbatim copies of the Program's source code as you +receive it, in any medium, provided that you conspicuously and +appropriately publish on each copy an appropriate copyright notice; +keep intact all notices stating that this License and any +non-permissive terms added in accord with section 7 apply to the code; +keep intact all notices of the absence of any warranty; and give all +recipients a copy of this License along with the Program. + +You may charge any price or no price for each copy that you convey, +and you may offer support or warranty protection for a fee. + +@item Conveying Modified Source Versions. + +You may convey a work based on the Program, or the modifications to +produce it from the Program, in the form of source code under the +terms of section 4, provided that you also meet all of these +conditions: + +@enumerate a +@item +The work must carry prominent notices stating that you modified it, +and giving a relevant date. + +@item +The work must carry prominent notices stating that it is released +under this License and any conditions added under section 7. This +requirement modifies the requirement in section 4 to ``keep intact all +notices''. + +@item +You must license the entire work, as a whole, under this License to +anyone who comes into possession of a copy. This License will +therefore apply, along with any applicable section 7 additional terms, +to the whole of the work, and all its parts, regardless of how they +are packaged. This License gives no permission to license the work in +any other way, but it does not invalidate such permission if you have +separately received it. + +@item +If the work has interactive user interfaces, each must display +Appropriate Legal Notices; however, if the Program has interactive +interfaces that do not display Appropriate Legal Notices, your work +need not make them do so. +@end enumerate + +A compilation of a covered work with other separate and independent +works, which are not by their nature extensions of the covered work, +and which are not combined with it such as to form a larger program, +in or on a volume of a storage or distribution medium, is called an +``aggregate'' if the compilation and its resulting copyright are not +used to limit the access or legal rights of the compilation's users +beyond what the individual works permit. Inclusion of a covered work +in an aggregate does not cause this License to apply to the other +parts of the aggregate. + +@item Conveying Non-Source Forms. + +You may convey a covered work in object code form under the terms of +sections 4 and 5, provided that you also convey the machine-readable +Corresponding Source under the terms of this License, in one of these +ways: + +@enumerate a +@item +Convey the object code in, or embodied in, a physical product +(including a physical distribution medium), accompanied by the +Corresponding Source fixed on a durable physical medium customarily +used for software interchange. + +@item +Convey the object code in, or embodied in, a physical product +(including a physical distribution medium), accompanied by a written +offer, valid for at least three years and valid for as long as you +offer spare parts or customer support for that product model, to give +anyone who possesses the object code either (1) a copy of the +Corresponding Source for all the software in the product that is +covered by this License, on a durable physical medium customarily used +for software interchange, for a price no more than your reasonable +cost of physically performing this conveying of source, or (2) access +to copy the Corresponding Source from a network server at no charge. + +@item +Convey individual copies of the object code with a copy of the written +offer to provide the Corresponding Source. This alternative is +allowed only occasionally and noncommercially, and only if you +received the object code with such an offer, in accord with subsection +6b. + +@item +Convey the object code by offering access from a designated place +(gratis or for a charge), and offer equivalent access to the +Corresponding Source in the same way through the same place at no +further charge. You need not require recipients to copy the +Corresponding Source along with the object code. If the place to copy +the object code is a network server, the Corresponding Source may be +on a different server (operated by you or a third party) that supports +equivalent copying facilities, provided you maintain clear directions +next to the object code saying where to find the Corresponding Source. +Regardless of what server hosts the Corresponding Source, you remain +obligated to ensure that it is available for as long as needed to +satisfy these requirements. + +@item +Convey the object code using peer-to-peer transmission, provided you +inform other peers where the object code and Corresponding Source of +the work are being offered to the general public at no charge under +subsection 6d. + +@end enumerate + +A separable portion of the object code, whose source code is excluded +from the Corresponding Source as a System Library, need not be +included in conveying the object code work. + +A ``User Product'' is either (1) a ``consumer product'', which means any +tangible personal property which is normally used for personal, +family, or household purposes, or (2) anything designed or sold for +incorporation into a dwelling. In determining whether a product is a +consumer product, doubtful cases shall be resolved in favor of +coverage. For a particular product received by a particular user, +``normally used'' refers to a typical or common use of that class of +product, regardless of the status of the particular user or of the way +in which the particular user actually uses, or expects or is expected +to use, the product. A product is a consumer product regardless of +whether the product has substantial commercial, industrial or +non-consumer uses, unless such uses represent the only significant +mode of use of the product. + +``Installation Information'' for a User Product means any methods, +procedures, authorization keys, or other information required to +install and execute modified versions of a covered work in that User +Product from a modified version of its Corresponding Source. The +information must suffice to ensure that the continued functioning of +the modified object code is in no case prevented or interfered with +solely because modification has been made. + +If you convey an object code work under this section in, or with, or +specifically for use in, a User Product, and the conveying occurs as +part of a transaction in which the right of possession and use of the +User Product is transferred to the recipient in perpetuity or for a +fixed term (regardless of how the transaction is characterized), the +Corresponding Source conveyed under this section must be accompanied +by the Installation Information. But this requirement does not apply +if neither you nor any third party retains the ability to install +modified object code on the User Product (for example, the work has +been installed in ROM). + +The requirement to provide Installation Information does not include a +requirement to continue to provide support service, warranty, or +updates for a work that has been modified or installed by the +recipient, or for the User Product in which it has been modified or +installed. Access to a network may be denied when the modification +itself materially and adversely affects the operation of the network +or violates the rules and protocols for communication across the +network. + +Corresponding Source conveyed, and Installation Information provided, +in accord with this section must be in a format that is publicly +documented (and with an implementation available to the public in +source code form), and must require no special password or key for +unpacking, reading or copying. + +@item Additional Terms. + +``Additional permissions'' are terms that supplement the terms of this +License by making exceptions from one or more of its conditions. +Additional permissions that are applicable to the entire Program shall +be treated as though they were included in this License, to the extent +that they are valid under applicable law. If additional permissions +apply only to part of the Program, that part may be used separately +under those permissions, but the entire Program remains governed by +this License without regard to the additional permissions. + +When you convey a copy of a covered work, you may at your option +remove any additional permissions from that copy, or from any part of +it. (Additional permissions may be written to require their own +removal in certain cases when you modify the work.) You may place +additional permissions on material, added by you to a covered work, +for which you have or can give appropriate copyright permission. + +Notwithstanding any other provision of this License, for material you +add to a covered work, you may (if authorized by the copyright holders +of that material) supplement the terms of this License with terms: + +@enumerate a +@item +Disclaiming warranty or limiting liability differently from the terms +of sections 15 and 16 of this License; or + +@item +Requiring preservation of specified reasonable legal notices or author +attributions in that material or in the Appropriate Legal Notices +displayed by works containing it; or + +@item +Prohibiting misrepresentation of the origin of that material, or +requiring that modified versions of such material be marked in +reasonable ways as different from the original version; or + +@item +Limiting the use for publicity purposes of names of licensors or +authors of the material; or + +@item +Declining to grant rights under trademark law for use of some trade +names, trademarks, or service marks; or + +@item +Requiring indemnification of licensors and authors of that material by +anyone who conveys the material (or modified versions of it) with +contractual assumptions of liability to the recipient, for any +liability that these contractual assumptions directly impose on those +licensors and authors. +@end enumerate + +All other non-permissive additional terms are considered ``further +restrictions'' within the meaning of section 10. If the Program as you +received it, or any part of it, contains a notice stating that it is +governed by this License along with a term that is a further +restriction, you may remove that term. If a license document contains +a further restriction but permits relicensing or conveying under this +License, you may add to a covered work material governed by the terms +of that license document, provided that the further restriction does +not survive such relicensing or conveying. + +If you add terms to a covered work in accord with this section, you +must place, in the relevant source files, a statement of the +additional terms that apply to those files, or a notice indicating +where to find the applicable terms. + +Additional terms, permissive or non-permissive, may be stated in the +form of a separately written license, or stated as exceptions; the +above requirements apply either way. + +@item Termination. + +You may not propagate or modify a covered work except as expressly +provided under this License. Any attempt otherwise to propagate or +modify it is void, and will automatically terminate your rights under +this License (including any patent licenses granted under the third +paragraph of section 11). + +However, if you cease all violation of this License, then your license +from a particular copyright holder is reinstated (a) provisionally, +unless and until the copyright holder explicitly and finally +terminates your license, and (b) permanently, if the copyright holder +fails to notify you of the violation by some reasonable means prior to +60 days after the cessation. + +Moreover, your license from a particular copyright holder is +reinstated permanently if the copyright holder notifies you of the +violation by some reasonable means, this is the first time you have +received notice of violation of this License (for any work) from that +copyright holder, and you cure the violation prior to 30 days after +your receipt of the notice. + +Termination of your rights under this section does not terminate the +licenses of parties who have received copies or rights from you under +this License. If your rights have been terminated and not permanently +reinstated, you do not qualify to receive new licenses for the same +material under section 10. + +@item Acceptance Not Required for Having Copies. + +You are not required to accept this License in order to receive or run +a copy of the Program. Ancillary propagation of a covered work +occurring solely as a consequence of using peer-to-peer transmission +to receive a copy likewise does not require acceptance. However, +nothing other than this License grants you permission to propagate or +modify any covered work. These actions infringe copyright if you do +not accept this License. Therefore, by modifying or propagating a +covered work, you indicate your acceptance of this License to do so. + +@item Automatic Licensing of Downstream Recipients. + +Each time you convey a covered work, the recipient automatically +receives a license from the original licensors, to run, modify and +propagate that work, subject to this License. You are not responsible +for enforcing compliance by third parties with this License. + +An ``entity transaction'' is a transaction transferring control of an +organization, or substantially all assets of one, or subdividing an +organization, or merging organizations. If propagation of a covered +work results from an entity transaction, each party to that +transaction who receives a copy of the work also receives whatever +licenses to the work the party's predecessor in interest had or could +give under the previous paragraph, plus a right to possession of the +Corresponding Source of the work from the predecessor in interest, if +the predecessor has it or can get it with reasonable efforts. + +You may not impose any further restrictions on the exercise of the +rights granted or affirmed under this License. For example, you may +not impose a license fee, royalty, or other charge for exercise of +rights granted under this License, and you may not initiate litigation +(including a cross-claim or counterclaim in a lawsuit) alleging that +any patent claim is infringed by making, using, selling, offering for +sale, or importing the Program or any portion of it. + +@item Patents. + +A ``contributor'' is a copyright holder who authorizes use under this +License of the Program or a work on which the Program is based. The +work thus licensed is called the contributor's ``contributor version''. + +A contributor's ``essential patent claims'' are all patent claims owned +or controlled by the contributor, whether already acquired or +hereafter acquired, that would be infringed by some manner, permitted +by this License, of making, using, or selling its contributor version, +but do not include claims that would be infringed only as a +consequence of further modification of the contributor version. For +purposes of this definition, ``control'' includes the right to grant +patent sublicenses in a manner consistent with the requirements of +this License. + +Each contributor grants you a non-exclusive, worldwide, royalty-free +patent license under the contributor's essential patent claims, to +make, use, sell, offer for sale, import and otherwise run, modify and +propagate the contents of its contributor version. + +In the following three paragraphs, a ``patent license'' is any express +agreement or commitment, however denominated, not to enforce a patent +(such as an express permission to practice a patent or covenant not to +sue for patent infringement). To ``grant'' such a patent license to a +party means to make such an agreement or commitment not to enforce a +patent against the party. + +If you convey a covered work, knowingly relying on a patent license, +and the Corresponding Source of the work is not available for anyone +to copy, free of charge and under the terms of this License, through a +publicly available network server or other readily accessible means, +then you must either (1) cause the Corresponding Source to be so +available, or (2) arrange to deprive yourself of the benefit of the +patent license for this particular work, or (3) arrange, in a manner +consistent with the requirements of this License, to extend the patent +license to downstream recipients. ``Knowingly relying'' means you have +actual knowledge that, but for the patent license, your conveying the +covered work in a country, or your recipient's use of the covered work +in a country, would infringe one or more identifiable patents in that +country that you have reason to believe are valid. + +If, pursuant to or in connection with a single transaction or +arrangement, you convey, or propagate by procuring conveyance of, a +covered work, and grant a patent license to some of the parties +receiving the covered work authorizing them to use, propagate, modify +or convey a specific copy of the covered work, then the patent license +you grant is automatically extended to all recipients of the covered +work and works based on it. + +A patent license is ``discriminatory'' if it does not include within the +scope of its coverage, prohibits the exercise of, or is conditioned on +the non-exercise of one or more of the rights that are specifically +granted under this License. You may not convey a covered work if you +are a party to an arrangement with a third party that is in the +business of distributing software, under which you make payment to the +third party based on the extent of your activity of conveying the +work, and under which the third party grants, to any of the parties +who would receive the covered work from you, a discriminatory patent +license (a) in connection with copies of the covered work conveyed by +you (or copies made from those copies), or (b) primarily for and in +connection with specific products or compilations that contain the +covered work, unless you entered into that arrangement, or that patent +license was granted, prior to 28 March 2007. + +Nothing in this License shall be construed as excluding or limiting +any implied license or other defenses to infringement that may +otherwise be available to you under applicable patent law. + +@item No Surrender of Others' Freedom. + +If conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot convey +a covered work so as to satisfy simultaneously your obligations under +this License and any other pertinent obligations, then as a +consequence you may not convey it at all. For example, if you agree +to terms that obligate you to collect a royalty for further conveying +from those to whom you convey the Program, the only way you could +satisfy both those terms and this License would be to refrain entirely +from conveying the Program. + +@item Use with the GNU Affero General Public License. + +Notwithstanding any other provision of this License, you have +permission to link or combine any covered work with a work licensed +under version 3 of the GNU Affero General Public License into a single +combined work, and to convey the resulting work. The terms of this +License will continue to apply to the part which is the covered work, +but the special requirements of the GNU Affero General Public License, +section 13, concerning interaction through a network will apply to the +combination as such. + +@item Revised Versions of this License. + +The Free Software Foundation may publish revised and/or new versions +of the GNU General Public License from time to time. Such new +versions will be similar in spirit to the present version, but may +differ in detail to address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies that a certain numbered version of the GNU General Public +License ``or any later version'' applies to it, you have the option of +following the terms and conditions either of that numbered version or +of any later version published by the Free Software Foundation. If +the Program does not specify a version number of the GNU General +Public License, you may choose any version ever published by the Free +Software Foundation. + +If the Program specifies that a proxy can decide which future versions +of the GNU General Public License can be used, that proxy's public +statement of acceptance of a version permanently authorizes you to +choose that version for the Program. + +Later license versions may give you additional or different +permissions. However, no additional obligations are imposed on any +author or copyright holder as a result of your choosing to follow a +later version. + +@item Disclaimer of Warranty. + +THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY +APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT +HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM ``AS IS'' WITHOUT +WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT +LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR +A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND +PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE +DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR +CORRECTION. + +@item Limitation of Liability. + +IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR +CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, +INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES +ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT +NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR +LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM +TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER +PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. + +@item Interpretation of Sections 15 and 16. + +If the disclaimer of warranty and limitation of liability provided +above cannot be given local legal effect according to their terms, +reviewing courts shall apply local law that most closely approximates +an absolute waiver of all civil liability in connection with the +Program, unless a warranty or assumption of liability accompanies a +copy of the Program in return for a fee. + +@end enumerate + +@heading END OF TERMS AND CONDITIONS + +@heading How to Apply These Terms to Your New Programs + +If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these +terms. + +To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +state the exclusion of warranty; and each file should have at least +the ``copyright'' line and a pointer to where the full notice is found. + +@smallexample +@var{one line to give the program's name and a brief idea of what it does.} +Copyright (C) @var{year} @var{name of author} + +This program is free software: you can redistribute it and/or modify +it under the terms of the GNU General Public License as published by +the Free Software Foundation, either version 3 of the License, or (at +your option) any later version. + +This program is distributed in the hope that it will be useful, but +WITHOUT ANY WARRANTY; without even the implied warranty of +MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

It +complements the GNU General Public License, which is a copyleft +license designed for free software. + +We have designed this License in order to use it for manuals for free +software, because free software needs free documentation: a free +program should come with manuals providing the same freedoms that the +software does. But this License is not limited to software manuals; +it can be used for any textual work, regardless of subject matter or +whether it is published as a printed book. We recommend this License +principally for works whose purpose is instruction or reference. + +@item +APPLICABILITY AND DEFINITIONS + +This License applies to any manual or other work, in any medium, that +contains a notice placed by the copyright holder saying it can be +distributed under the terms of this License. Such a notice grants a +world-wide, royalty-free license, unlimited in duration, to use that +work under the conditions stated herein. The ``Document'', below, +refers to any such manual or work. Any member of the public is a +licensee, and is addressed as ``you''. You accept the license if you +copy, modify or distribute the work in a way requiring permission +under copyright law. + +A ``Modified Version'' of the Document means any work containing the +Document or a portion of it, either copied verbatim, or with +modifications and/or translated into another language. + +A ``Secondary Section'' is a named appendix or a front-matter section +of the Document that deals exclusively with the relationship of the +publishers or authors of the Document to the Document's overall +subject (or to related matters) and contains nothing that could fall +directly within that overall subject. (Thus, if the Document is in +part a textbook of mathematics, a Secondary Section may not explain +any mathematics.) The relationship could be a matter of historical +connection with the subject or with related matters, or of legal, +commercial, philosophical, ethical or political position regarding +them. + +The ``Invariant Sections'' are certain Secondary Sections whose titles +are designated, as being those of Invariant Sections, in the notice +that says that the Document is released under this License. If a +section does not fit the above definition of Secondary then it is not +allowed to be designated as Invariant. The Document may contain zero +Invariant Sections. If the Document does not identify any Invariant +Sections then there are none. + +The ``Cover Texts'' are certain short passages of text that are listed, +as Front-Cover Texts or Back-Cover Texts, in the notice that says that +the Document is released under this License. A Front-Cover Text may +be at most 5 words, and a Back-Cover Text may be at most 25 words. + +A ``Transparent'' copy of the Document means a machine-readable copy, +represented in a format whose specification is available to the +general public, that is suitable for revising the document +straightforwardly with generic text editors or (for images composed of +pixels) generic paint programs or (for drawings) some widely available +drawing editor, and that is suitable for input to text formatters or +for automatic translation to a variety of formats suitable for input +to text formatters. A copy made in an otherwise Transparent file +format whose markup, or absence of markup, has been arranged to thwart +or discourage subsequent modification by readers is not Transparent. +An image format is not Transparent if used for any substantial amount +of text. A copy that is not ``Transparent'' is called ``Opaque''. + +Examples of suitable formats for Transparent copies include plain +@sc{ascii} without markup, Texinfo input format, La@TeX{} input +format, @acronym{SGML} or @acronym{XML} using a publicly available +@acronym{DTD}, and standard-conforming simple @acronym{HTML}, +PostScript or @acronym{PDF} designed for human modification. Examples +of transparent image formats include @acronym{PNG}, @acronym{XCF} and +@acronym{JPG}. Opaque formats include proprietary formats that can be +read and edited only by proprietary word processors, @acronym{SGML} or +@acronym{XML} for which the @acronym{DTD} and/or processing tools are +not generally available, and the machine-generated @acronym{HTML}, +PostScript or @acronym{PDF} produced by some word processors for +output purposes only. + +The ``Title Page'' means, for a printed book, the title page itself, +plus such following pages as are needed to hold, legibly, the material +this License requires to appear in the title page. For works in +formats which do not have any title page as such, ``Title Page'' means +the text near the most prominent appearance of the work's title, +preceding the beginning of the body of the text. + +A section ``Entitled XYZ'' means a named subunit of the Document whose +title either is precisely XYZ or contains XYZ in parentheses following +text that translates XYZ in another language. (Here XYZ stands for a +specific section name mentioned below, such as ``Acknowledgements'', +``Dedications'', ``Endorsements'', or ``History''.) To ``Preserve the Title'' +of such a section when you modify the Document means that it remains a +section ``Entitled XYZ'' according to this definition. + +The Document may include Warranty Disclaimers next to the notice which +states that this License applies to the Document. These Warranty +Disclaimers are considered to be included by reference in this +License, but only as regards disclaiming warranties: any other +implication that these Warranty Disclaimers may have is void and has +no effect on the meaning of this License. + +@item +VERBATIM COPYING + +You may copy and distribute the Document in any medium, either +commercially or noncommercially, provided that this License, the +copyright notices, and the license notice saying this License applies +to the Document are reproduced in all copies, and that you add no other +conditions whatsoever to those of this License. You may not use +technical measures to obstruct or control the reading or further +copying of the copies you make or distribute. However, you may accept +compensation in exchange for copies. If you distribute a large enough +number of copies you must also follow the conditions in section 3. + +You may also lend copies, under the same conditions stated above, and +you may publicly display copies. + +@item +COPYING IN QUANTITY + +If you publish printed copies (or copies in media that commonly have +printed covers) of the Document, numbering more than 100, and the +Document's license notice requires Cover Texts, you must enclose the +copies in covers that carry, clearly and legibly, all these Cover +Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on +the back cover. Both covers must also clearly and legibly identify +you as the publisher of these copies. The front cover must present +the full title with all words of the title equally prominent and +visible. You may add other material on the covers in addition. +Copying with changes limited to the covers, as long as they preserve +the title of the Document and satisfy these conditions, can be treated +as verbatim copying in other respects. + +If the required texts for either cover are too voluminous to fit +legibly, you should put the first ones listed (as many as fit +reasonably) on the actual cover, and continue the rest onto adjacent +pages. + +If you publish or distribute Opaque copies of the Document numbering +more than 100, you must either include a machine-readable Transparent +copy along with each Opaque copy, or state in or with each Opaque copy +a computer-network location from which the general network-using +public has access to download using public-standard network protocols +a complete Transparent copy of the Document, free of added material. +If you use the latter option, you must take reasonably prudent steps, +when you begin distribution of Opaque copies in quantity, to ensure +that this Transparent copy will remain thus accessible at the stated +location until at least one year after the last time you distribute an +Opaque copy (directly or through your agents or retailers) of that +edition to the public. + +It is requested, but not required, that you contact the authors of the +Document well before redistributing any large number of copies, to give +them a chance to provide you with an updated version of the Document. + +@item +MODIFICATIONS + +You may copy and distribute a Modified Version of the Document under +the conditions of sections 2 and 3 above, provided that you release +the Modified Version under precisely this License, with the Modified +Version filling the role of the Document, thus licensing distribution +and modification of the Modified Version to whoever possesses a copy +of it. In addition, you must do these things in the Modified Version: + +@enumerate A +@item +Use in the Title Page (and on the covers, if any) a title distinct +from that of the Document, and from those of previous versions +(which should, if there were any, be listed in the History section +of the Document). You may use the same title as a previous version +if the original publisher of that version gives permission. + +@item +List on the Title Page, as authors, one or more persons or entities +responsible for authorship of the modifications in the Modified +Version, together with at least five of the principal authors of the +Document (all of its principal authors, if it has fewer than five), +unless they release you from this requirement. + +@item +State on the Title page the name of the publisher of the +Modified Version, as the publisher. + +@item +Preserve all the copyright notices of the Document. + +@item +Add an appropriate copyright notice for your modifications +adjacent to the other copyright notices. + +@item +Include, immediately after the copyright notices, a license notice +giving the public permission to use the Modified Version under the +terms of this License, in the form shown in the Addendum below. + +@item +Preserve in that license notice the full lists of Invariant Sections +and required Cover Texts given in the Document's license notice. + +@item +Include an unaltered copy of this License. + +@item +Preserve the section Entitled ``History'', Preserve its Title, and add +to it an item stating at least the title, year, new authors, and +publisher of the Modified Version as given on the Title Page. If +there is no section Entitled ``History'' in the Document, create one +stating the title, year, authors, and publisher of the Document as +given on its Title Page, then add an item describing the Modified +Version as stated in the previous sentence. + +@item +Preserve the network location, if any, given in the Document for +public access to a Transparent copy of the Document, and likewise +the network locations given in the Document for previous versions +it was based on.

Emacs already helps you with editing +files, but Emacs can do much more. In particular, looking up +documentation is one of its strong points.

This can be done with the MIX virtual machine. First you will +need to compile your code into MIX byte code. This can be done within +Emacs with the command @kbd{M-x compile} (@kbd{C-c c}). In case of +compilation errors, you can jump to the offending source code line +with @kbd{M-x next-error}. + +Once the program compiles without errors, you can debug or run +it.

While in Knuth's definition of MIXAL each field must start at a +fixed pre-defined column number, the @sc{mdk} assembler loosens this +requirement and lets you format the file as you see fit. The only +restrictions retained are for comment lines (like 1-4) which must begin +with an asterisk (*) placed at column 1, and for the label field (see +below) which, if present, must also start at column 1. The four fields +in each non-comment line are: + +@itemize @minus +@item +an optional label, which either refers to the current memory address (as +@code{START} and @code{MSG} in lines 7 and 9) or a defined symbol +(@code{TERM}) (if present, the label must always start at the first +column in its line, for the first whitespace in the line marks the +beginning of the second field), +@item +an operation mnemonic, which can represent either a MIX instruction +(@code{OUT} and @code{HLT} in lines 7 and 8 above), or an assembly +pseudoinstruction (e.g., the @code{ORIG} pseudoinstruction in line +6@footnote{If an @code{ORIG} directive is not used, the program will +be loaded by the virtual machine at address 0. @code{ORIG} allows +allocating the executable code where you see fit.}. +@item +an optional operand for the (pseudo)instruction, and +@item +an optional free text comment. +@end itemize + +@noindent Lines 9-12 of the @file{hello.mixal} file above also show the +second (and last) difference between Knuth's MIXAL definition and ours: +the operand of the @code{ALF} pseudoinstruction (a word of five +characters) must be quoted using ""@footnote{In Knuth's definition, +the operand always starts at a fixed column number, and the use of +quotation is therefore unnecessary. As @code{mixasm} releases this +requirement, marking the beginning and end of the @code{ALF} operand +disambiguates the parser's recognition of this operand when it includes +blanks.

They are + +@itemize @bullet +@item +@code{mixvm}, a command line oriented simulator, +@item +@code{gmixvm}, a GTK based graphical interface to @code{mixvm}, and +@item +@code{mixguile}, a Guile shell with a built-in MIX simulator. +@end itemize + +All three simulators accept the same set of user commands, but offer a +different user interface, as noted above. In this section we shall +describe some of these commands, and show you how to use them from +@code{mixvm}'s command line. You can use them as well at @code{gmixvm}'s +command prompt (@pxref{gmixvm}), or using the built-in Scheme primitives +of @code{mixguile} (@pxref{Using mixguile}). + +Using the MIX simulators, you can run your MIXAL programs, after +compiling them with @code{mixasm} into binary @file{.mix} +files. @code{mixvm} can be used either in @dfn{interactive} or +@dfn{non-interactive} mode. In the second case, @code{mixvm} will load +your program into memory, execute it (producing any output due to +MIXAL @code{OUT} instructions present in the program), and exit when +it encounters a @code{HLT} instruction. In interactive mode, you will +enter a shell prompt which allows you issuing commands to the running +virtual machine. These commands will permit you to load, run and debug +programs, as well as to inspect the MIX computer state (register +contents, memory cells contents and so on). + +@menu +* Non-interactive mode:: Running your programs non-interactively. +* Interactive mode:: Running programs interactively. +* Debugging:: Commands for debugging your programs. +@end menu + +@node Non-interactive mode, Interactive mode, Running the program, Running the program +@comment node-name, next, previous, up +@subsection Non-interactive mode +@cindex non-interactive mode + +To make @code{mixvm} work in non-interactive mode, use the @code{-r} +flag. Thus, to run our @file{hello.mix} program, simply type + +@example +mixvm -r hello @key{RET} +@end example + +@noindent at your command prompt, and you will get the following output: + +@example +MIXAL HELLO WORLD +@end example + +@noindent Since our hello world program uses MIX's device number 19 as +its output device (@pxref{Writing a source file}), the output is +redirected to the shell's standard output. Had you used any other MIX +output devices (disks, drums, line printer, etc.), @code{mixvm} would +have created a file named after the device used (e.g. @file{disk4.dev}) +and written its output there@footnote{The device files are stored, by +default, in a directory called @file{.mdk}, which is created in your +home directory the first time @code{mixvm} is run. You can change this +default directory using the command @code{devdir} when running +@code{mixvm} in interactive mode (@pxref{Configuration commands})}. + +The virtual machine can also report the execution time of the program, +according to the (virtual) time spent in each of the binary instructions +(@pxref{Execution times}). Printing of execution time statistics is +activated with the @code{-t} flag; running + +@example +mixvm -t -r hello @key{RET} +@end example + +@noindent +produces the following output: + +@example +MIXAL HELLO WORLD +** Execution time: 11 +@end example + +Sometimes, you will prefer to store the results of your program in MIX +registers rather than writing them to a device. In such cases, +@code{mixvm}'s @code{-d} flag is your friend: it makes @code{mixvm} +dump the contents of its registers and flags after executing the loaded +program. For instance, typing the following command at your shell's +prompt + +@example +mixvm -d -r hello +@end example + +@noindent you will obtain the following output: + +@example +MIXAL HELLO WORLD +rA: + 00 00 00 00 00 (0000000000) +rX: + 00 00 00 00 00 (0000000000) +rJ: + 00 00 (0000) +rI1: + 00 00 (0000) rI2: + 00 00 (0000) +rI3: + 00 00 (0000) rI4: + 00 00 (0000) +rI5: + 00 00 (0000) rI6: + 00 00 (0000) +Overflow: F +Cmp: E +@end example + +@noindent which, in addition to the program's outputs and execution +time, gives you the contents of the MIX registers and the values of the +overflow toggle and comparison flag (admittedly, rather uninteresting in +our sample). + +As you can see, running programs non-interactively has many +limitations. You cannot peek the virtual machine's memory contents, not +to mention stepping through your program's instructions or setting +breakpoints@footnote{The @code{mixguile} program allows you to execute +arbitrary combinations of @code{mixvm} commands (using Scheme) +non-interactively. @xref{Scheme scripts}.}.

You will be presented the following command +prompt: + +@example +MIX > +@end example + +@noindent The virtual machine is initialised and ready to accept your +commands. The @code{mixvm} command shell uses GNU's readline, so that +you have at your disposal command completion (using @key{TAB}) and +history functionality, as well as other line editing shortcuts common to +all utilities using this library (for a complete description of +readline's line editing usage, see @ref{Command Line +Editing,,,Readline}.) + +@cindex @code{load} +Usually, the first thing you will want to do is loading a compiled MIX +program into memory. This is accomplished by the @code{load} command, +which takes as an argument the name of the @file{.mix} file to be +loaded. Thus, typing + +@example +MIX > load hello @key{RET} +Program loaded. Start address: 3000 +MIX > +@end example + +@noindent will load @file{hello.mix} into the virtual machine's memory +and set the program counter to the address of the first instruction.

You obtain the +elapsed execution time (i.e., the time spent executing instructions +since the last breakpoint), the total execution time for the program up +to now (which in our case coincides with the elapsed time, since there +were no breakpoints), and the total uptime for the virtual machine (you +can load and run more than one program in the same +session)@footnote{Printing of timing statistics can be disabled using +the command @code{timing} (@pxref{Configuration commands}).}. After +running the program, the program counter will point to the address after +the one containing the @code{HLT} instruction. In our case, asking the +value of the program counter after executing the program will give us + +@example +MIX > pc +Current address: 3002 +MIX > +@end example + +@cindex @code{pmem} +@noindent You can check the contents of a memory cell giving its address +as an argument of the command @code{pmem}, like this + +@example +MIX > pmem 3001 +3001: + 00 00 00 02 05 (0000000133) +MIX > +@end example + +@noindent +and convince yourself that address 3001 contains the binary +representation of the instruction @code{HLT}. An address range of the +form FROM-TO can also be used as the argument of @code{pmem}: + +@example +MIX > pmem 3000-3006 +3000: + 46 58 00 19 37 (0786957541) +3001: + 00 00 00 02 05 (0000000133) +3002: + 14 09 27 01 13 (0237350989) +3003: + 00 08 05 13 13 (0002118477) +3004: + 16 00 26 16 19 (0268542995) +3005: + 13 04 00 00 00 (0219152384) +3006: + 00 00 00 00 00 (0000000000) +MIX > +@end example + +@cindex @code{preg} +@noindent +In a similar manner, you can look at the contents of the MIX registers +and flags.

Use @code{next} to step through +the program, running its instructions one by one. To run our +two-instruction @file{hello.mix} sample you can do the following: + +@example +MIX > load hello +Program loaded. Start address: 3000 +MIX > pc +Current address: 3000 +MIX > next +MIXAL HELLO WORLD +Elapsed time: 1 /Total program time: 1 (Total uptime: 1) +MIX > pc +Current address: 3001 +MIX > next +End of program reached at address 3002 +Elapsed time: 10 /Total program time: 11 (Total uptime: 11) +MIX > pc +Current address: 3002 +MIX > next +MIXAL HELLO WORLD +Elapsed time: 1 /Total program time: 1 (Total uptime: 12) +MIX > +MIX > run +Running ... +... done +Elapsed time: 10 /Total program time: 11 (Total uptime: 22) +MIX > +@end example +@noindent +(As an aside, the above sample also shows how the virtual machine +handles cumulative time statistics and automatic program restart). + +@cindex @code{sbpa} +@cindex breakpoints + +You can set a breakpoint at a given address using the command +@code{sbpa} (set breakpoint at address). When a breakpoint is set, +@code{run} will stop before executing the instruction at the given +address. Typing @code{run} again will resume program execution. Coming +back to our hello world example, we would have: + +@example +MIX > sbpa 3001 +Breakpoint set at address 3001 +MIX > run +Running ... +MIXAL HELLO WORLD +... stopped: breakpoint at line 8 (address 3001) +Elapsed time: 1 /Total program time: 1 (Total uptime: 23) +MIX > run +Running ... +... done +Elapsed time: 10 /Total program time: 11 (Total uptime: 33) +MIX > +@end example + +@cindex @code{sbp} +@cindex breakpoints +@noindent +Note that, since we compiled @file{hello.mixal} with debug info +enabled, the virtual machine is able to tell us the line in the +source file corresponding to the breakpoint we are setting. As a +matter of fact, you can directly set breakpoints at source code lines +using the command @code{sbp LINE_NO}, e.g. + +@example +MIX > sbp 4 +Breakpoint set at line 7 +MIX > +@end example + +@noindent +@code{sbp} sets the breakpoint at the first meaningful source code line; +thus, in the above example we have requested a breakpoint at a line +which does not correspond to a MIX instruction and the breakpoint is set +at the first line containing a real instruction after the given one. To +unset breakpoints, use @code{cbpa ADDRESS} and @code{cbp LINE_NO}, or +@code{cabp} to remove all currently set breakpoints. You can also set +conditional breakpoints, i.e., tell @code{mixvm} to interrupt program +execution whenever a register, a memory cell, the comparison flag or the +overflow toggle change using the commands @w{@code{sbp[rmco]}} +(@pxref{Debug commands}). + +@cindex @code{psym} +MIXAL lets you define symbolic constants, either using the @code{EQU} +pseudoinstruction or starting an instruction line with a label (which +assigns to the label the value of the current memory address). Each +MIXAL program has, therefore, an associated symbol table which you can +inspect using the @code{psym} command. For our hello world sample, you +will obtain the following output: + +@example +MIX > psym +START: 3000 +TERM: 19 +MSG: 3002 +MIX > +@end example + +Other useful commands for debugging are @code{strace} (which turns on +tracing of executed instructions), @code{pbt} (which prints a backtrace +of executed instructions) and @code{weval} (which evaluates +w-expressions on the fly). For a complete description of all available +MIX commands, @xref{mixvm}. + +@node Using mixguile, Using Scheme in mixvm and gmixvm, Running the program, Getting started +@section Using @code{mixguile} + +With @code{mixguile} you can run a MIX simulator embedded in a Guile +shell, that is, using Scheme functions and programs.

But, in case +you are wondering, this is only the beginning. You also have at your +disposal a whole Scheme interpreter, and you can, for instance, define +new functions combining the @code{mix-} and all other Scheme +primitives. In the next sections, you'll find examples of how to take +advantage of the Guile interpreter. + +@node Additional functions, Defining new functions, The mixguile shell, Using mixguile +@subsection Additional MIX Scheme functions + +The @code{mix-} function counterparts of the @code{mixvm} commands don't +return any value, and are evaluated only for their side-effects +(possibly including informational messages to the standard output and/or +error stream). When writing your own Scheme functions to manipulate the +MIX virtual machine within @code{mixguile} (@pxref{Defining new +functions}), you'll probably need Scheme functions returning the value +of the registers, memory cells and so on. Don't worry: @code{mixguile} +also offers you such functions. For instance, to access the (numerical) +value of a register you can use @code{mix-reg}: + +@example +guile> (mix-reg 'I2) +0 +guile> +@end example +@noindent +Note that, unlike @code{(mix-preg 'I2)}, the expression @code{(mix-reg +'I2)} in the above example evaluates to a Scheme number and does not +produce any side-effect: + +@example +guile> (number? (mix-reg 'I2)) +#t +guile> (number? (mix-preg 'I2)) +rI2: + 00 00 (0000) +#f +guile> +@end example + +In a similar fashion, you can access the memory contents using +@code{(mix-cell)}, or the program counter using @code{(mix-loc)}: + +@example +guile> (mix-cell 3000) +786957541 +guile> (mix-loc) +3002 +guile> +@end example + +Other functions returning the contents of the virtual machine components +are @code{mix-cmp} and @code{mix-over}, which eval to the value of the +comparison flag and the overflow toggle respectively.

Frequently, +you'll write new functions that improve in some way the workings of a +built-in @code{mixvm} command, following this pattern: + +@enumerate a +@item +Prepare the command execution +@item +Execute the desired command +@item +Perform post execution operations +@end enumerate + +We call the functions executed in step (a) @dfn{pre-hook}s, and those of +step @dfn{post-hook}s of the given command. @code{mixguile} lets you +specify pre- and post-hooks for any @code{mixvm} command using the +@code{mix-add-pre-hook} and @code{mix-add-post-hook} functions, which +take as arguments a symbol naming the command and a function to be +executed before (resp. after) the command. In other words, +@code{mixguile} will execute for you steps (a) and (c) above whenever +you eval (b). The hook functions must take a single argument, which is a +string list of the command's arguments. As an example, let us define the +following hooks for the @code{next} command: + +@example +(define next-pre-hook + (lambda (arglist) + (mix-slog #f))) + +(define next-post-hook + (lambda (arglist) + (display "Stopped at line ") + (display (mix-src-line-no)) + (display ": ") + (display (mix-src-line)) + (newline) + (mix-slog #t))) +@end example +@noindent +In these functions, we are using the function @code{mix-slog} to turn +off the informational messages produced by the virtual machine, since we +are providing our own ones in the post hook function. To install these +hooks, we would write: + +@example +(mix-add-pre-hook 'next next-pre-hook) +(mix-add-post-hook 'next next-post-hook) +@end example +@noindent +Assuming we have put the above expressions in @code{mixguile}'s +initialisation file, we would obtain the following results when +evaluating @code{mix-next}: + +@example +guile> (mix-next) +MIXAL HELLO WORLD +Stopped at line 6: HLT +guile> +@end example + +As a second, more elaborate, example, let's define hooks which print +the address and contents of a cell being modified using @code{smem}. The +hook functions could be something like this: + +@example +(define smem-pre-hook + (lambda (arglist) + (if (eq? (length arglist) 2) + (begin + (display "Changing address ") + (display (car arglist)) + (newline) + (display "Old contents: ") + (display (mix-cell (string->number (car arglist)))) + (newline)) + (error "Wrong arguments" arglist)))) + +(define smem-post-hook + (lambda (arglist) + (if (eq? (length arglist) 2) + (begin + (display "New contents: ") + (display (mix-cell (string->number (car arglist)))) + (newline))))) +@end example +@noindent +and we can install them using + +@example +(mix-add-pre-hook 'smem smem-pre-hook) +(mix-add-post-hook 'smem smem-post-hook) +@end example +@noindent +Afterwards, a sample execution of @code{mix-smem} would look like this: + +@example +guile> (mix-smem 2000 100) +Changing address 2000 +Old contents: 0 +New contents: 100 +guile> +@end example + +@cindex global hook + +You can add any number of hooks to a given command. They will be +executed in the same order as they are registered. You can also define +global post (pre) hooks, which will be called before (after) any +@code{mixvm} command is executed. Global hook functions must admit two +arguments, namely, a string naming the invoked command and a string list +of its arguments, and they are installed using the Scheme functions +@code{mix-add-global-pre-hook} and @code{mix-add-global-post-hook}. A +simple example of global hook would be: + +@example +guile> (define pre-hook + (lambda (cmd args) + (display cmd) + (display " invoked with arguments ") + (display args) + (newline))) +guile> (mix-add-global-pre-hook pre-hook) +ok +guile> (mix-pmem 120 125) +pmem invoked with arguments (120-125) +0120: + 00 00 00 00 00 (0000000000) +0121: + 00 00 00 00 00 (0000000000) +0122: + 00 00 00 00 00 (0000000000) +0123: + 00 00 00 00 00 (0000000000) +0124: + 00 00 00 00 00 (0000000000) +0125: + 00 00 00 00 00 (0000000000) +guile> +@end example + +Note that if you invoke @code{mixvm} commands within a global hook, its +associated command hooks will be run. Thus, if you have installed both +the @code{next} hooks described earlier and the global hook above, +executing @code{mix-next} will yield the following result: + +@example +guile> (mix-next 5) +next invoked with arguments (5) +slog invoked with arguments (off) +MIXAL HELLO WORLD +Stopped at line 7: MSG ALF "MIXAL" +slog invoked with arguments (on) +guile> +@end example + +Adventurous readers may see the above global hook as the beginning of a +command log utility or a macro recorder that saves your commands for +replay. + +@node Break hooks, , Command hooks, Hook functions +@subsubsection Break hooks + +@cindex break hook + +We have seen in the previous section how to associate hooks to command +execution, but they are not the whole story. You can also associate hook +functions to program interruption, that is, specify functions that +should be called every time the execution of a MIX program is stopped +due to the presence of a breakpoint, either explicit or +conditional. Break hooks take as arguments the line number and memory +address at which the break occurred. A simple hook that logs the line +and address of the breakpoint could be defined as: + +@example +(define break-hook + (lambda (line address) + (display "Breakpoint encountered at line ") + (display line) + (display " and address ") + (display address) + (newline))) +@end example +@noindent +and installed for explicit and conditional breakpoints using + +@example +(mix-add-break-hook break-hook) +(mix-add-cond-break-hook break-hook) +@end example +@noindent +after that, every time the virtual machine encounters a breakpoint, +@code{break-code} shall be evaluated for you@footnote{You may have +noticed that break hooks can be implemented in terms of command hooks +associated to @code{mix-run} and @code{mix-next}. As a matter of fact, +they @emph{are} implemented this way: take a look at the file +@file{@emph{install_dir}/share/mdk/mix-vm-stat.scm} if you are curious.}. + +@node Scheme scripts, , Hook functions, Using mixguile +@subsection Scheme scripts +@cindex Scheme script +@cindex non-interactive + +Another useful way of using @code{mixguile} is writing executable +scripts that perform a set of commands for you. This is done using the +@code{mixguile} switch @code{-s} (being a Guile shell, @code{mixguile} +accepts all the command options of @code{guile}; type @code{mixguile -h} +for a list of all available command options). For instance, if you have +a very useful MIX program @file{foo.mix} which you want to run often, +you don't have to fire up a MIX virtual machine, load and run it every +time; you can write a Scheme script instead: + +@example +#! /usr/bin/mixguile -s +!# +;;; runprimes: execute the primes.mix program + +;; load the file you want to run +(mix-load "../samples/primes") +;; execute it +(mix-run) +;; print the contents of registers +(mix-pall) +;; ... +@end example + +Just save the above script to a file named, say, @file{runtest}, make it +executable (@code{chmod +x runtest}), and, well, execute it from the +Unix shell: + +@example +$ ./runtest +Program loaded.

For additional +@code{mixguile} command line options, see @ref{Invoking mixguile}. + +@node Using Scheme in mixvm and gmixvm, , Using mixguile, Getting started +@section Using Scheme in @code{mixvm} and @code{gmixvm} +@cindex @code{scmf} + +In the previous section (@pxref{Using mixguile}) we have seen how the +Guile shell @code{mixguile} offers you the possibility of using Scheme +to manipulate a MIX virtual machine and extend the set of commands +offered by @code{mixvm} and @code{gmixvm}. This possibility is not +limited to the @code{mixguile} shell. Actually, both @code{mixvm} and +@code{gmixvm} incorporate an embedded Guile interpreter, and can +evaluate Scheme expressions. To evaluate a single-line expression at the +@code{mixvm} or @code{gmixvm} command prompt, simply write it and press +return (the command parser will recognise it as a Scheme expression +because it is parenthesized, and will pass it to the Guile +interpreter). A sample @code{mixvm} session using Scheme expressions +could be: + +@example +MIX > load hello +Program loaded.

In other words, these programs +are extensible using Scheme.

Knuth uses an imaginary computer, the MIX, and its +associated machine-code and assembly languages to illustrate the +concepts and algorithms as they are presented. + +The MIX's architecture is a simplified version of those found in real +CISC CPUs, and the MIX assembly language (MIXAL) provides a set of +primitives that will be very familiar to any person with a minimum +experience in assembly programming. The MIX/MIXAL definition is powerful +and complete enough to provide a virtual development platform for +writing quite complex programs, and close enough to real computers to be +worth using when learning programming techniques. At any rate, if you +want to learn or improve your programming skills, a MIX development +environment would come in handy. + +The @sc{mdk} package aims at providing such virtual development +environment on a GNU box. Thus, @sc{mdk} offers you a set of utilities +to simulate the MIX computer and to write, compile, run and debug MIXAL +programs. As of version @value{VERSION}, @sc{mdk} includes +the following programs: + +@table @code +@item mixasm +MIXAL assembler. Assembler which translates MIXAL source files into +programs that can be run (and debugged) by @code{mixvm}, @code{mixguile} +or @code{gmixvm}. +@item mixvm +MIX virtual machine. Emulation of the MIX computer with a @acronym{CLI}. +@item gmixvm +A GTK+ GUI for the MIX virtual machine.

These binary programs could be written by hand, but it is +easier to produce them compiling MIXAL source files, using the MIXAL +assembler @code{mixasm}. On the other hand, @code{mixguile} offers you +the possibility of manipulating a MIX virtual machine through a set of +Scheme functions, so that you can use this programming language to +interact with the virtual machine.

Conversely, @code{mixvm} and @code{gmixvm} contain +a Guile interpreter, and are able to use this same Scheme library, as +well as all the other Guile/Scheme primitives and any user defined +function. Therefore, you have at your disposal a powerful programming +language, Scheme, to extend the @sc{mdk} virtual machine emulators (see +@ref{Using Scheme in mixvm and gmixvm} for samples of how to do it). + +The following subsections describe available functions the MIX/Scheme +library. + +@menu +* mixvm wrappers:: Functions invoking mixvm commands. +* Hooks:: Adding hooks to mixvm commands. +* Additional VM functions:: Functions accessing the MIX virtual machine. +@end menu + +@node mixvm wrappers, Hooks, Scheme functions reference, Scheme functions reference +@subsection @code{mixvm} command wrappers + +For each of the @code{mixvm} commands listed in @ref{Commands}, there is +a corresponding Scheme function named by prefixing the command name with +@code{mix-} (e.g., @code{mix-load}, @code{mix-run} and so on). These +command wrappers are implemented using a generic command dispatching +function: + +@defun mixvm-cmd command argument +Dispatches the given @var{command} to the MIX virtual machine appending the +provided @var{argument}. Both @var{command} and @code{argument} must be +strings. The net result is as writing "@var{command} @var{argument}" at +the @code{mixvm} or @code{gmixvm} command prompt. +@end defun + +For instance, you can invoke the @code{run} command at the @code{mixvm} +prompt in three equivalent ways: + +@example +MIX > run hello +MIX > (mix-run "hello") +MIX > (mixvm-cmd "run" "hello") +@end example +@noindent +(only the two last forms can be used at the @code{mixguile} prompt or +inside a Scheme script). + +The @code{mix-} functions evaluate to a unspecified value. If you want +to check the result of the last @code{mixvm} command invocation, use the +@code{mix-last-result} function: + +@defun mix-last-result +Returns @var{#t} if the last @code{mixvm} command invocation was +successful, @var{#f} otherwise. +@end defun +@noindent +Using this function, we could improve the script for running a program +presented in the previous section by adding error checking: + + +@example +#! /usr/bin/mixguile \ +-e main -s +!# + +;;; Execute a given program and print the registers. + +(define main + (lambda (args) + ;; load the file provided as a command line argument + (mix-load (cadr args)) + ;; execute it if mix-load succeeded + (if (mix-last-result) (mix-run)) + ;; print the contents of registers if the above commands succeeded + (if (mix-last-result) (mix-pall)))) +@end example + +Please, refer to @ref{Commands} for a list of available commands. Given +the description of a @code{mixvm}, it is straightforward to use its +Scheme counterpart and, therefore, we shall not give a complete +description of these functions here. Instead, we will only mention those +wrappers that exhibit a treatment of their differing from that of their +command counterpart. + +@defun mix-preg [register] +@defunx mix-sreg register value +The argument @var{register} of these functions can be either a string or +a symbol representing the desired register. For instance, the following +invocations are equivalent: + +@example +(mix-preg 'I1) +(mix-preg "I1") +@end example +@end defun + +@defun mix-pmem from [to] +The command @code{pmem} takes a single argument which can be either a +cell number or a range of the form @code{FROM-TO}. This function takes +one argument to ask for a single memory cell contents, or two parameters +to ask for a range. For instance, the following commands are equivalent: + +@example +MIX > pmem 10-12 +0010: + 00 00 00 00 00 (0000000000) +0011: + 00 00 00 00 00 (0000000000) +0012: + 00 00 00 00 00 (0000000000) +MIX > (mix-pmem 10 12) +0010: + 00 00 00 00 00 (0000000000) +0011: + 00 00 00 00 00 (0000000000) +0012: + 00 00 00 00 00 (0000000000) +MIX > +@end example +@end defun + +@defun mix-sover #t|#f +The command @code{sover} takes as argument either the string @code{T} or +the string @code{F}, to set, respectively, the overflow toggle to true +or false. Its Scheme counterpart, @code{mix-sover}, takes as argument +a Scheme boolean value: @code{#t} (true) or @code{#f}. +@end defun + +For the remaining functions, you simply must take into account that when +the command arguments are numerical, the corresponding Scheme function +takes as arguments Scheme number literals. On the other hand, when the +command argument is a string, the argument of its associated Scheme +function will be a Scheme string. By way of example, the following +invocations are pairwise equivalent: + +@example +MIX > load ../samples/hello +MIX > (mix-load "../samples/hello") + +MIX > next 5 +MIX > (mix-next 5) +@end example + +@node Hooks, Additional VM functions, mixvm wrappers, Scheme functions reference +@subsection Hook functions + +Hooks are functions evaluated before or after executing a @code{mixvm} +command (or its corresponding Scheme function wrapper), or after an +explicit or conditional breakpoint is found during the execution of a +MIX program. The following functions let you install hooks: + +@defun mix-add-pre-hook command hook +Adds a function to the list of pre-hooks associated with the given +@var{command}. @var{command} is a string naming the corresponding @code{mixvm} +command, and @var{hook} is a function which takes a single argument: a +string list of the commands arguments. The following scheme code defines +a simple hook and associates it with the @code{run} command: + +@example +(define run-hook + (lambda (args) + (display "argument list: ") + (display args) + (newline))) +(mix-add-pre-hook "run" run-hook) +@end example + +Pre-hooks are executed, in the order they are added, before invoking the +corresponding command (or its associated Scheme wrapper function). +@end defun + +@defun mix-add-post-hook command hook +Adds a function to the list of pre-hooks associated with the given +@var{command}. The arguments have the same meaning as in +@code{mix-add-pre-hook}. +@end defun + +@defun mix-add-global-pre-hook hook +@defunx mix-add-global-post-hook hook +Global pre/post hooks are executed before/after any @code{mixvm} command +or function wrapper invocation. In this case, @var{hook} takes two +arguments: a string with the name of the command being invoked, and a +string list with its arguments. +@end defun + +@defun mix-add-break-hook hook +@defunx mix-add-cond-break hook +Add a hook funtion to be executed when an explicit (resp. conditional) +breakpoint is encountered during program execution. @var{hook} is a +function taking two arguments: the source line number where the hook has +occurred, and the current program counter value. The following code +shows a simple definition and installation of a break hook: + +@example +(define break-hook + (lambda (line address) + (display "Breakpoint at line ") (display line) + (display " and address ") (display address) + (newline))) +(mix-add-break-hook break-hook) +@end example + +Break hook functions are entirely implemented in Scheme using regular +post-hooks for the @code{next} and @code{run} commands. If you are +curious, you can check the Scheme source code at +@file{@emph{prefix}/share/mdk/mixguile-vm-stat.scm} (where @emph{prefix} +stands for your root install directory, usually @code{/usr} or +@code{/usr/local}. +@end defun + + +See @ref{Hook functions} for further examples on using hook functions. + + +@node Additional VM functions, , Hooks, Scheme functions reference +@subsection Additional VM functions + +When writing non-trivial Scheme extensions using the MIX/Scheme library, +you will probably need to evaluate the contents of the virtual machine +components (registers, memory cells and so on). For instance, you may +need to store the contents of the @code{A} register in a variable. The +Scheme functions described so far are of no help: you can print the +contents of @code{A} using @code{(mix-preg 'A)}, but you cannot define a +variable containing the contents of @code{A}. To address this kind of +problems, the MIX/Scheme library provides the following additional +functions: + +@defun mixvm-status +@defunx mix-vm-status +Return the current status of the virtual machine, as a number +(@code{mixvm-status}) or as a symbol (@code{mix-vm-status}). Possible +return values are: +@multitable {aamixvmaastatusaa} {aamixvmastatusaaaaaaa} {return valuesaaaaaaaaaaaaaaaaaaaaaaaaaa} +@item @code{(mixvm-status)} @tab @code{(mix-vm-status)} @tab +@item 0 @tab MIX_ERROR @tab Loading or execution error +@item 1 @tab MIX_BREAK @tab Breakpoint encountered +@item 2 @tab MIX_COND_BREAK @tab Conditional breakpoint +@item 3 @tab MIX_HALTED @tab Execution terminated +@item 4 @tab MIX_RUNNING @tab Execution stopped after @code{next} +@item 5 @tab MIX_LOADED @tab Program successfully loaded +@item 6 @tab MIX_EMPTY @tab No program loaded +@end multitable +@end defun + +@defun mix-vm-error? +@defunx mix-vm-break? +@defunx mix-vm-cond-break? +@defunx mix-vm-halted? +@defunx mix-vm-running? +@defunx mix-vm-loaded? +@defunx mix-vm-empty? +Predicates asking whether the current virtual machine status is +@code{MIX_ERROR}, @code{MIX_BREAK}, etc. +@end defun + +@defun mix-reg register +@defunx mix-set-reg! register value +@code{mix-reg} evaluates to a number which is the contents of the +specified @var{register}. @code{mix-set-reg} sets the contents of the +given @var{register} to @var{value}. The register can be specified +either as a string (@code{"A"}, @code{"X"}, etc.) or as a symbol +(@code{'A}, @code{'X}, etc.). For instance, + +@example +guile> (mix-reg 'A) +2341 +guile> (mix-set-reg! "A" 2000) +ok +guile> (define reg-a (mix-reg 'A)) +guile> (display reg-a) +2000 +guile> +@end example +@end defun + +@defun mix-cell cell_no +@defunx mix-set-cell! cell_no value +Evaluate and set the contents of the memory cell number +@var{cell_no}. Both @var{cell_no} and @var{value} are Scheme numbers. +@end defun + +@defun mix-loc +Evaluates to the value of the location counter (i.e., the address of the +next instruction to be executed). +@end defun + +@defun mix-over +@defunx mix-set-over! #t|#f +@code{mix-over} evaluates to @code{#t} if the overflow toggle is set, +and to @code{#f} otherwise. The value of the overflow toggle can be +modified using @code{mix-set-over!}. +@end defun + +@defun mix-cmp +@defunx mix-set-cmp! 'L|'E|'G +Evaluate and set the comparison flag.

Execution is interrupted either when the specified +number of instructions have been fetched or a breakpoint is found, +whatever happens first. If run without arguments, one instruction is +executed. If @code{next} is invoked again after program execution +completion (i.e., after the @code{HLT} instruction has been found in a +previous run), the program counter is repositioned and execution starts +again from the beginning (as a matter of fact, a @code{load} command +preserving the currently set breakpoints is issued before resuming +execution). +@end deffn + +@deffn {debug command} sbp line_number +@deffnx {debug command} cbp line_no +Sets a breakpoint at the specified source file line number.

The symbol table can be consulted from +the @code{mixvm} command line using @code{psym} followed by the name of +the symbol whose contents you are interested in. When run without +arguments, @code{psym} will print all defined symbols and their values. +@end deffn + +The virtual machine can also show you the instructions it is executing, +using the following commands: + +@deffn {debug command} strace [on|off] +@code{strace on} enables instruction tracing. When tracing is enabled, +each time the virtual machine executes an instruction (due to your +issuing a @code{run} or @code{next} command), it is printed in its +canonical form (that is, with all expressions evaluated to their +numerical values) and, if the program was compiled with debug +information, as it was originally typed in the MIXAL source +file. Instruction tracing is disabled with @code{strace off} +command.

When you request an output operation on any other +(output) device, a file named according to the following table will be +created, and the specified MIX words will be +written to the file in binary form (for binary devices) or in ASCII (for +char devices). Files corresponding to input block devices should be +created and filled beforehand to be used by the MIX virtual machine (for +input-output devices this creation can be accomplished by a MIXAL +program writing to the device the required data, or, if you prefer, with +your favourite editor). The device files are stored, by default, in the +directory @file{~/.mdk}; this location can be changed using the +@code{mixvm} command @code{devdir} (@pxref{Configuration commands}). + +@multitable {the device name} { xx-xx } {filename[x-x].dev} {bin i/o/char } +@item @emph{Device} @tab @emph{No.} @tab @emph{filename} @tab @emph{type and block size} +@item Tape @tab 0-7 @tab @file{tape[0-7].dev} @tab bin i/o - 100 words +@item Disks @tab 8-15 @tab @file{disk[0-7].dev} @tab bin i/o - 100 words +@item Card reader @tab 16 @tab @file{cardrd.dev} @tab char in - 16 words +@item Card writer @tab 17 @tab @file{cardwr.dev} @tab char out - 16 words +@item Line printer @tab 18 @tab @file{printer.dev} @tab char out - 24 words +@item Terminal @tab 19 @tab @code{stdin/stdout} @tab char i/o - 14 words +@item Paper tape @tab 20 @tab @file{paper.dev} @tab char in - 14 words +@end multitable + +Devices of type @i{char} are stored as ASCII files, using one line per +block.

If the reader finds a line with less than the +required number of characters, it pads the memory with zeroes (MIX +character 'space') to complete the block size. + +Note that the virtual machine automatically converts between the MIX and +ASCII character encodings, so that you can manipulate char device files +with any ASCII editor. In addition, the reader is not case-sensitive, +i.e., it automatically converts lowercase letters to their uppercase +counterparts (since the MIX character set does not include the former). + +The typewriter (device no. 19) lets you use the standard input and +output in your MIXAL programs.

Note that a +MIX byte can be then represented as 6 bits, instead of the common 8 bits +for a @emph{regular} byte. Unless otherwise stated, we shall use the +word @dfn{byte} to refer to a MIX 6-bit byte. + +A MIX @dfn{word} is defined as a set of 5 bytes plus a sign. The bytes +within a word are numbered from 1 to 5, being byte number one the most +significant one. The sign is denoted by index 0. Graphically, + +@example + ----------------------------------------------- +| 0 | 1 | 2 | 3 | 4 | 5 | + ----------------------------------------------- +| +/- | byte | byte | byte | byte | byte | + ----------------------------------------------- +@end example +@noindent +Sample MIX words are @samp{- 12 00 11 01 63} and @samp{+ 12 11 34 43 +00}. + +You can refer to subfields within a word using a @dfn{field +specification} or @dfn{fspec} of the form ``(@var{L}:@var{R})'', where +@var{L} denotes the first byte, and @var{R} the last byte of the +subfield. +When @var{L} is zero, the subfield includes the word's +sign. An fspec can also be represented as a single value @code{F}, given +by @code{F = 8*L + R} (thus the fspec @samp{(1:3)}, denoting the first +three bytes of a word, is represented by the integer 11). + +The MIX computer stores information in @dfn{registers}, that can store +either a word or two bytes and sign (see below), and @dfn{memory cells}, +each one containing a word. Specifically, the MIX computer has 4000 +memory cells with addresses 0 to 3999 (i.e., two bytes are enough to +address a memory cell) and the following registers: + +@cindex rA +@cindex rX +@cindex rJ +@cindex rIn +@cindex register + +@table @asis +@item @code{rA} +A register. General purpose register holding a word. Usually its +contents serves as the operand of arithmetic and storing instructions. +@item @code{rX} +X register. General purpose register holding a word. Often it acts as an +extension or a replacement of @samp{rA}. +@item @code{rJ} +J (jump) register.

These six registers can store a signed two-byte +value.

In this manual, this toggle is denoted @sc{ov}. +@item +A @dfn{comparison indicator} (having three values: @dfn{EQUAL}, +@dfn{GREATER} or @dfn{LESS}). In this manual, this indicator is denoted +@sc{cm}, and its possible values are abbreviated as @dfn{E}, @dfn{G} and +@dfn{L}. +@item +Input-output block devices. Each device is labelled as @code{un}, where +@code{n} runs from 0 to 20. In Knuth's definition, @code{u0} through +@code{u7} are magnetic tape units, @code{u8} through @code{15} are disks +and drums, @code{u16} is a card reader, @code{u17} is a card writer, +@code{u18} is +a line printer and, @code{u19} is a typewriter terminal, and @code{u20}, +a paper tape. Our implementation maps these devices to disk files, +except for @code{u19}, which represents the standard output. +@end itemize + +As noted above, the MIX computer communicates with the external world by +a set of input-output devices which can be ``connected'' to it.

In multiplication +and division, the register @samp{X} comes into play as a right-extension +of the register @samp{A}, so that we are able to handle 10-byte numbers +whose more significant bytes are those of @samp{rA} (the sign of this +10-byte number is that of @samp{rA}: @samp{rX}'s sign is ignored). + +Addition and subtraction of MIX words can give rise to overflows, since +the result is stored in a register with room to only 5 bytes (plus +sign).

You cannot directly modify the contents +of this internal register with a load instruction: after fetching the +current instruction from memory, it is automatically increased in one +unit by the MIX. However, there is a set of instructions (which we call +jump instructions) which can alter the contents of the location counter +provided some condition is met. When this occurs, the value of the next +instruction address that would have been fetched in the absence of the +jump is stored in @samp{rJ} (except for @code{JSJ}), and the location +counter is set to the value of @samp{M} (so that the next instruction is +fetched from this new address).

Loosely speaking, we will be interested in the answer to the +question: how long does it take a program to execute? Of course, this +execution time will be a function of the input size, and the answer to +our question is commonly given as the asymptotic behaviour as a +function of the input size. At any rate, to compute this asymptotic +behaviour, we need a measure of how long execution of a single +instruction takes in our (virtual) CPU. Therefore, each MIX +instruction will have an associated execution time, given in arbitrary +units (in a real computer, the value of this unit will depend on the +hardware configuration). When our MIX virtual machine executes +programs, it will (optionally) give you the value of their execution +time based upon the execution time of each single instruction. + +In the following table, the execution times (in the above mentioned +arbitrary units) of the MIX instructions are given. + +@multitable {INSSSS} {01} {INSSSS} {01} {INSSSS} {01} {INSSSS} {01} +@item @code{NOP} @tab 1 @tab @code{ADD} @tab 2 @tab @code{SUB} +@tab 2 @tab @code{MUL} @tab 10 +@item @code{DIV} @tab 12 @tab @code{NUM} @tab 10 @tab @code{CHAR} +@tab 10 @tab @code{HLT} @tab 10 +@item @code{SLx} @tab 2 @tab @code{SRx} @tab 2 @tab @code{LDx} +@tab 2 @tab @code{STx} @tab 2 +@item @code{JBUS} @tab 1 @tab @code{IOC} @tab 1 @tab @code{IN} +@tab 1@tab @code{OUT} @tab 1 +@item @code{JRED} @tab 1 @tab @code{Jx} @tab 1 @tab @code{INCx} +@tab 1 @tab @code{DECx} @tab 1 +@item @code{ENTx} @tab 1 @tab @code{ENNx} @tab 1 @tab @code{CMPx} +@tab 1 @tab @code{MOVE} @tab 1+2F +@end multitable + +In the above table, 'F' stands for the number of blocks to be moved +(given by the @code{FSPEC} subfield of the instruction); @code{SLx} and +@code{SRx} are a short cut for the byte-shifting operations; @code{LDx} +denote all the loading operations; @code{STx} are the storing +operations; @code{Jx} stands for all the jump operations, and so on with +the rest of abbreviations. + +@node MIXAL, , The MIX computer, MIX and MIXAL tutorial +@comment node-name, next, previous, up +@section MIXAL +@cindex MIXAL +@cindex MIX assembly language +@cindex assembly + +In the previous sections we have listed all the available MIX binary +instructions. As we have shown, each instruction is represented by a +word which is fetched from memory and executed by the MIX virtual +CPU. As is the case with real computers, the MIX knows how to decode +instructions in binary format (the so--called machine language), but a +human programmer would have a tough time if she were to write her +programs in machine language. Fortunately, the MIX computer can be +programmed using an assembly language, MIXAL, which provides a symbolic +way of writing the binary instructions understood by the imaginary MIX +computer. If you have used assembler languages before, you will find +MIXAL a very familiar language. MIXAL source files are translated +to machine language by a MIX assembler, which produces a binary file (the +actual MIX program) which can be directly loaded into the MIX memory and +subsequently executed. + +In this section, we describe MIXAL, the MIX assembly language. The +implementation of the MIX assembler program and MIX computer simulator +provided by @sc{mdk} are described later on (@pxref{Getting started}). + +@menu +* Basic structure:: Writing basic MIXAL programs. +* MIXAL directives:: Assembler directives. +* Expressions:: Evaluation of expressions. +* W-expressions:: Evaluation of w-expressions. +* Local symbols:: Special symbol table entries. +* Literal constants:: Specifying an immediate operand. +@end menu + +@node Basic structure, MIXAL directives, MIXAL, MIXAL +@comment node-name, next, previous, up +@subsection Basic program structure + +The MIX assembler reads MIXAL files line by line, producing, when +required, a binary instruction, which is associated to a predefined +memory address. To keep track of the current address, the assembler +maintains an internal location counter which is incremented each time an +instruction is compiled. In addition to MIX instructions, you can +include in MIXAL file assembly directives (or pseudoinstructions) +addressed at the assembler itself (for instance, telling it where the +program starts and ends, or to reposition the location counter; see below). + +MIX instructions and assembler directives@footnote{We shall call them, +collectively, MIXAL instructions.} are written in MIXAL (one per +source file line) according to the following pattern: + +@example +[LABEL] MNEMONIC [OPERAND] [COMMENT] +@end example + +@noindent +where @samp{OPERAND} is of the form + +@example +[ADDRESS][,INDEX][(MOD)] +@end example + +Items between square brackets are optional, and + +@table @code +@item LABEL +is an alphanumeric identifier (a @dfn{symbol}) which gets the current +value of the location counter, and can be used in subsequent +expressions, +@item MNEMONIC +is a literal denoting the operation code of the instruction +(e.g. @code{LDA}, @code{STA}; see @pxref{MIX instruction set}) or an +assembly pseudoinstruction (e.g. @code{ORG}, @code{EQU}), +@item ADDRESS +is an expression evaluating to the address subfield of the instruction, +@item INDEX +is an expression evaluating to the index subfield of the instruction, which +defaults to 0 (i.e., no use of indexing) and can only be used when +@code{ADDRESS} is present, +@item MOD +is an expression evaluating to the mod subfield of the instruction. Its +default value, when omitted, depends on @code{OPCODE}, +@item COMMENT +any number of spaces after the operand mark the beginning of a comment, +i.e. any text separated by white space from the operand is ignored by +the assembler (note that spaces are not allowed within the +@samp{OPERAND} field). +@end table + +Note that spaces are @emph{not} allowed between the @code{ADDRESS}, +@code{INDEX} and @code{MOD} fields if they are present. White space is +used to separate the label, operation code and operand parts of the +instruction@footnote{In fact, Knuth's definition of MIXAL restricts the +column number at which each of these instruction parts must start. The +MIXAL assembler included in @sc{mdk}, @code{mixasm}, does not impose +such restriction.}. + +We have already listed the mnemonics associated with each MIX +instruction; sample MIXAL instructions representing MIX instructions +are: +@example +HERE LDA 2000 HERE represents the current location counter + LDX HERE,2(1:3) this is a comment + JMP 1234 +@end example + +@node MIXAL directives, Expressions, Basic structure, MIXAL +@comment node-name, next, previous, up +@subsection MIXAL directives + +MIXAL instructions can be either one of the MIX machine instructions +(@pxref{MIX instruction set}) or one of the following assembly +pseudoinstructions: + +@ftable @code +@item ORIG +Sets the value of the memory address to which following instructions +will be allocated after compilation. +@item EQU +Used to define a symbol's value, e.g. @w{@code{SYM EQU 2*200/3}}. +@item CON +The value of the given expression is copied directly into the current +memory address. +@item ALF +Takes as operand five characters, constituting the five bytes of a word +which is copied directly into the current memory address. +@item END +Marks the end of the program. Its operand gives the start address for +program execution. +@end ftable + +The operand of @code{ORIG}, @code{EQU}, @code{CON} and @code{END} can be +any expression evaluating to a constant MIX word, i.e., either a simple +MIXAL expression (composed of numbers, symbols and binary operators, +@pxref{Expressions}) or a w-expression (@pxref{W-expressions}). + +All MIXAL programs must contain an @code{END} directive, with a twofold +end: first, it marks the end of the assembler job, and, in the second +place, its (mandatory) operand indicates the start address for the +compiled program (that is, the address at which the virtual MIX machine +must begin fetching instructions after loading the program). It is also +very common (although not mandatory) to include at least an @code{ORIG} +directive to mark the initial value of the assembler's location counter +(remember that it stores the address associated with each compiled MIX +instruction). Thus, a minimal MIXAL program would be + +@example + ORIG 2000 set the initial compilation address + NOP this instruction will be loaded at address 2000 + HLT and this one at address 2001 + END 2000 end of program; start at address 2000 +this line is not parsed by the assembler +@end example +@noindent +The assembler will generate two binary instructions (@code{NOP} (@w{+ 00 +00 00 00 00}) and @code{HLT} (+ 00 00 02 05)), which will be loaded at +addresses 2000 and 2001. Execution of the program will begin at address +2000. Every MIXAL program should also include a @code{HLT} instruction, +which will mark the end of program execution (but not of program +compilation). + +The @code{EQU} directive allows the definition of symbolic names for +specific values. For instance, we could rewrite the above program as +follows: + +@example +START EQU 2000 + ORIG START + NOP + HLT + END START +@end example +@noindent +which would give rise to the same compiled code. Symbolic constants (or +symbols, for short) can also be implicitly defined placing them in the +@code{LABEL} field of a MIXAL instruction: in this case, the assembler +assigns to the symbol the value of the location counter before compiling +the line. Hence, a third way of writing our trivial program is + +@example + ORIG 2000 +START NOP + HLT + END START +@end example + +The @code{CON} directive allows you to directly specify the contents of +the memory address pointed by the location counter. For instance, when +the assembler encounters the following code snippet + +@example + ORIG 1150 + CON -1823473 +@end example +@noindent +it will assign to the memory cell number 1150 the contents @w{- 00 06 61 +11 49} (which corresponds to the decimal value -1823473). + +Finally, the @code{ALF} directive lets you specify the memory contents +as a set of five (optionally quoted) characters, which are translated by +the assembler to their byte values, conforming in that way the binary +word that is to be stored in the corresponding memory cell. This +directive comes in handy when you need to store printable messages in a +memory address, as in the following example @footnote{In the original +MIXAL definition, the @code{ALF} argument is not quoted. You can write +the operand (as the @code{ADDRESS} field) without quotes, but, in this +case, you must follow the alignment rules of the original MIXAL +definition (namely, the @code{ADDRESS} must start at column 17).}: + +@example + OUT MSG MSG is not yet defined here (future reference) +MSG ALF "THIS " MSG gets defined here + ALF "IS A " + ALF "MESSA" + ALF "GE. " +@end example +@noindent +The above snippet also shows the use of a @dfn{future reference}, that +is, the usage of a symbol (@code{MSG} in the example) prior of its actual +definition. The MIXAL assembler is able to handle future references +subject to some limitations which are described in the following section +(@pxref{Expressions}). + +@cindex comments + +Any line starting with an asterisk is treated as a comment and ignored +by the assembler. + +@example +* This is a comment: this line is ignored. + * This line is an error: * must be in column 1. +@end example + +As noted in the previous section, comments can also be located after the +@code{OPERAND} field of an instruction, separated from it by white +space, as in + +@example +LABEL LDA 100 This is also a comment +@end example + +@node Expressions, W-expressions, MIXAL directives, MIXAL +@comment node-name, next, previous, up +@subsection Expressions +@cindex operator +@cindex binary operator +@cindex unary operator +The @code{ADDRESS}, @code{INDEX} and @code{MOD} fields of a MIXAL +instruction can be expressions, formed by numbers, identifiers and +binary operators (@code{+ - * / // :}). @code{+} and @code{-} can also +be used as unary operators. Operator precedence is from left to right: +there is no other operator precedence rule, and parentheses cannot be +used for grouping. A stand-alone asterisk denotes the current memory +location; thus, for instance, + +@example + 4+2** +@end example + +@noindent +evaluates to 6 (4 plus 2) times the current memory location. White space +is not allowed within expressions. + +The special binary operator @code{:} has the same meaning as in fspecs, +i.e., + +@example +A:B = 8*A + B +@end example +@noindent +while @code{A//B} stands for the quotient of the ten-byte number @w{@code{A} 00 +00 00 00 00} (that is, A right-padded with 5 null bytes or, what amounts +to the same, multiplied by 64 to the fifth power) divided by +@code{B}. Sample expressions are: + +@example +18-8*3 = 30 +14/3 = 4 +1+3:11 = 4:11 = 43 +1//64 = (01 00 00 00 00 00)/(00 00 00 01 00) = (01 00 00 00 00) +@end example +@noindent +Note that all MIXAL expressions evaluate to a MIX word (by definition). + +All symbols appearing within an expression must be previously defined. Future +references are only allowed when appearing standalone (or modified by +an unary operator) in the @code{ADDRESS} part of a MIXAL instruction, +e.g. + +@example +* OK: stand alone future reference + STA -S1(1:5) +* ERROR: future reference in expression + LDX 2-S1 +S1 LD1 2000 +@end example + +@node W-expressions, Local symbols, Expressions, MIXAL +@comment node-name, next, previous, up +@subsection W-expressions +@cindex w-expressions + +Besides expressions, as described above (@pxref{Expressions}), the MIXAL +assembler is able to handle the so called @dfn{w-expressions} as the +operands of the directives @code{ORIG}, @code{EQU}, @code{CON} and +@code{END} (@pxref{MIXAL directives}). The general form of a +w-expression is the following: + +@example + WEXP = EXP[(EXP)][,WEXP] +@end example +@noindent +where @code{EXP} stands for an expression and square brackets denote +optional items. Thus, a w-expression is made by an expression, followed +by an optional expression between parenthesis, followed by any number +of similar constructs separated by commas. Sample w-expressions are: + +@example +2000 +235(3) +S1+3(S2),3000 +S1,S2(3:5),23 +@end example + +W-expressions are evaluated from left to right as follows: + +@itemize +@item +Start with an accumulated result @samp{w} equal to 0. +@item +Take the first expression of the comma-separated list and evaluate +it. For instance, if the w-expression is @samp{S1+2(2:4),2000(S2)}, we +evaluate first @samp{S1+2}; let's suppose that @samp{S1} equals +265230: then @samp{S1+2 = 265232 = + 00 01 00 48 16}. +@item +Evaluate the expression within parenthesis, reducing it to an f-spec +of the form @samp{L:R}. In our previous example, the expression +between parenthesis already has the desired form: 2:4. +@item +Substitute the bytes of the accumulated result @samp{w} designated by +the f-spec using those of the previous expression value. In our sample, +@samp{w = + 00 00 00 00 00}, and we must substitute bytes 2, 3 and 4 of +@samp{w} using values from 265232. We need 3 bytes, and we take the +least significant ones: 00, 48, and 16, and insert them in positions +2, 3 and 4 of @samp{w}, obtaining @samp{w = + 00 00 48 16 00}. +@item +Repeat this operation with the remaining terms, acting on the new +value of @samp{w}. In our example, if, say, @samp{S2 = 1:1}, we must +substitute the first byte of @samp{w} using one byte (the least +significant) from 2000, that is, 16 (since 2000 = + 00 00 00 31 16) +and, therefore, we obtain @samp{w = + 16 00 48 16 00}; summing up, we +have obtained @samp{265232(1:4),2000(1:1) = + 16 00 48 16 00 = +268633088}. +@end itemize + +As a second example, in the w-expression +@example +1(1:2),66(4:5) +@end example +@noindent +we first take two bytes from 1 (00 and 01) and store them as bytes 1 and +2 of the result (obtaining @w{@samp{+ 00 01 00 00 00}}) and, afterwards, +take two bytes from 66 (01 and 02) and store them as bytes 4 and 5 of +the result, obtaining @w{@samp{+ 00 01 00 01 02}} (262210). The process +is repeated for each new comma-separated example. For instance: + +@example +1(1:1),2(2:2),3(3:3),4(4:4) = 01 02 03 04 00 +@end example + +As stated before, w-expressions can only appear as the operands of MIXAL +directives taking a constant value (@code{ORIG}, @code{EQU}, @code{CON} +and @code{END}). Future references are @emph{not} allowed within +w-expressions (i.e., all symbols appearing in a w-expression must be +defined before it is used). + +@node Local symbols, Literal constants, W-expressions, MIXAL +@comment node-name, next, previous, up +@subsection Local symbols +@cindex local symbols + +Besides user defined symbols, MIXAL programmers can use the so called +@dfn{local symbols}, which are symbols of the form @code{[1-9][HBF]}. A +local symbol @code{nB} refers to the address of the last previous +occurrence of @code{nH} as a label, while @code{nF} refers to the next +@code{nH} occurrence. Unlike user defined symbols, @code{nH} can appear +multiple times in the @code{LABEL} part of different MIXAL +instructions. The following code shows an instance of local symbols' +usage: + +@example +* line 1 +1H LDA 100 +* line 2: 1B refers to address of line 1, 3F refers to address of line 4 + STA 3F,2(1B//2) +* line 3: redefinition of 1H +1H STZ +* line 4: 1B refers to address of line 3 +3H JMP 1B +@end example + +Note that a @code{B} local symbol never refers to a definition in its +own line, that is, in the following program: + +@example + ORIG 1999 +ST NOP +3H EQU 69 +3H ENTA 3B local symbol 3B refers to 3H in previous line + HLT + END ST +@end example +@noindent +the contents of @samp{rA} is set to 69 and @emph{not} to 2001.

For instance, the +code + +@example +L EQU 5 + LDA =20-L= +@end example + +causes the assembler to add after the program's end an instruction +with contents 15 (@samp{20-L}), and to assemble the above code as the +instruction @w{@code{ LDA a}}, where @code{a} stands for the address +in which the value 15 is stored.

The +dnl default (if it is not specified or empty) is 'no-libtool'. +dnl INTLSYMBOL should be 'external' for packages with no intl directory, +dnl and 'no-libtool' or 'use-libtool' for packages with an intl directory. +dnl If INTLSYMBOL is 'use-libtool', then a libtool library +dnl $(top_builddir)/intl/libintl.la will be created (shared and/or static, +dnl depending on --{enable,disable}-{shared,static} and on the presence of +dnl AM-DISABLE-SHARED). If INTLSYMBOL is 'no-libtool', a static library +dnl $(top_builddir)/intl/libintl.a will be created. +dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext +dnl implementations (in libc or libintl) without the ngettext() function +dnl will be ignored. If NEEDSYMBOL is specified and is +dnl 'need-formatstring-macros', then GNU gettext implementations that don't +dnl support the ISO C 99 <inttypes.h> formatstring macros will be ignored. +dnl INTLDIR is used to find the intl libraries. If empty, +dnl the value `$(top_builddir)/intl/' is used. +dnl +dnl The result of the configuration is one of three cases: +dnl 1) GNU gettext, as included in the intl subdirectory, will be compiled +dnl and used. +dnl Catalog format: GNU --> install in $(datadir) +dnl Catalog extension: .mo after installation, .gmo in source tree +dnl 2) GNU gettext has been found in the system's C library. +dnl Catalog format: GNU --> install in $(datadir) +dnl Catalog extension: .mo after installation, .gmo in source tree +dnl 3) No internationalization, always use English msgid. +dnl Catalog format: none +dnl Catalog extension: none +dnl If INTLSYMBOL is 'external', only cases 2 and 3 can occur. +dnl The use of .gmo is historical (it was needed to avoid overwriting the +dnl GNU format catalogs when building on a platform with an X/Open gettext), +dnl but we keep it in order not to force irrelevant filename changes on the +dnl maintainers. +dnl +AC_DEFUN([AM_GNU_GETTEXT], +[ + dnl Argument checking. + ifelse([$1], [], , [ifelse([$1], [external], , [ifelse([$1], [no-libtool], , [ifelse([$1], [use-libtool], , + [errprint([ERROR: invalid first argument to AM_GNU_GETTEXT +])])])])]) + ifelse([$2], [], , [ifelse([$2], [need-ngettext], , [ifelse([$2], [need-formatstring-macros], , + [errprint([ERROR: invalid second argument to AM_GNU_GETTEXT +])])])]) + define(gt_included_intl, ifelse([$1], [external], [no], [yes])) + define(gt_libtool_suffix_prefix, ifelse([$1], [use-libtool], [l], [])) + + AC_REQUIRE([AM_PO_SUBDIRS])dnl + ifelse(gt_included_intl, yes, [ + AC_REQUIRE([AM_INTL_SUBDIR])dnl + ]) + + dnl Prerequisites of AC_LIB_LINKFLAGS_BODY. + AC_REQUIRE([AC_LIB_PREPARE_PREFIX]) + AC_REQUIRE([AC_LIB_RPATH]) + + dnl Sometimes libintl requires libiconv, so first search for libiconv. + dnl Ideally we would do this search only after the + dnl if test "$USE_NLS" = "yes"; then + dnl if test "$gt_cv_func_gnugettext_libc" != "yes"; then + dnl tests.

It is typically used for file + * name completion as is common in many UNIX shells. + * + * A #Completion is created using completion_new(). Target items are + * added and removed with completion_add_items(), + * completion_remove_items() and completion_clear_items(). A + * completion attempt is requested with completion_complete() or + * completion_complete_utf8(). When no longer needed, the + * #Completion is freed with completion_free(). + * + * Items in the completion can be simple strings (e.g. filenames), or + * pointers to arbitrary data structures. If data structures are used + * you must provide a #CompletionFunc in completion_new(), which + * retrieves the item's string from the data structure. You can change + * the way in which strings are compared by setting a different + * #CompletionStrncmpFunc in completion_set_compare(). + * + * Completion has been marked as deprecated, since this API is rarely + * used and not very actively maintained. + **/ + +/** + * Completion: + * @items: list of target items (strings or data structures). + * @func: function which is called to get the string associated with a + * target item. It is %NULL if the target items are strings. + * @prefix: the last prefix passed to completion_complete() or + * completion_complete_utf8(). + * @cache: the list of items which begin with @prefix. + * @strncmp_func: The function to use when comparing strings.
