+<h2>Syntax</h2>
+
+<dl>
+<dt>(open-binary <i>file</i> [:direction <i>in-out</i>])</dt>
+<dd><i>file</i> - a string expression or symbol<br>
+<i>in-out</i> - an optional keyword symbol that must be either ':input' or
+':output'. The default is ':input'.<br>
+returns - a stream</dd>
+</dl>
+
+<h2>Description</h2>
+
+<p>The '<nobr>open-binary</nobr>' function opens the 'file' for binary input
+or output. The 'file' may be a string expression or a symbol. Following the
+'file', there is an optional keyword, ':direction'. The argument following
+this is either ':input' or ':output' which specifies the direction of the
+file. <nobr>If no</nobr> ':direction' is specified, the default is ':input'.
+When 'file' is a string, you may specify a complete file location or
+extensions like &quot;/usr/local/bin/myfile.lsp&quot; or
+&quot;A:\LISP\TIM.BAT&quot;. <nobr>If the</nobr> file open was successful,
+then a file pointer of the following form is returned as the result:</p>
+
+<pre class="example">
+#&lt;File: #99999&gt;
+</pre>
+
+<p>If the file open was not successful, a <a href="nil.htm">NIL</a> is
+returned. <nobr>For an</nobr> input file, the file has to exist, or an error
+will be signaled.</p>
+
+<h2>Examples</h2>
+
+<pre class="example">
+
+</pre>
+
+<p>This will create a file named FOO-FILE, because XLISP uppercases its
+symbols:</p>
+
+<pre class="example">
+(open-binary 'foo-file :direction :output)
+</pre>
+
+<p>This will create a file named 'foo-file' because UNIX doesn't
+uppercase its file names:</p>
+
+<pre class="example">
+(open-binary "foo-file" :direction :output)
+</pre>
+
+<p>So, if you are having trouble with opening and accessing files, check to
+make sure the file name is in the proper case.</p>
