<title>Initialization</title>
<para>
<emphasis>p1</emphasis> -- Number of times to repeat the section.

<para>

<title>Performance</title>
<para>
In order that the sections may be more flexible than simple editing, the macro named p2 is given the value of 1 for the first time through the section, 2 for the second, and 3 for the third. This can be used to change p-field parameters, or ignored.
</para>
<warning>
<title>Warning</title>
<para>
Because of serious problems of interaction with macro expansion, sections must start and end in the same file, and not in a macro.
