<title>UK TeX FAQ -- question label seccntfmt</title>

<h3>Adjusting the presentation of section numbers</h3>
<p/>The general issues of adjusting the appearance of section headings are
pretty complex, and are covered in
the question on
<a href="FAQ-secthead.html">the style of section headings</a>.
<p/>However, people regularly want merely to change the way the section
number appears in the heading, and some such people don’t mind writing
out a few macros. This answer is for <em>them</em>.
<p/>The section number is typeset using the
<a href="FAQ-atsigns.html">LaTeX internal</a>
<code>\</code><code>@seccntformat</code> command, which is given the “name” (section,
subsection, …) of the heading, as argument. Ordinarily,
<code>\</code><code>@seccntformat</code>
merely outputs the section number, and then a <code>\</code><code>quad</code> of space:
<blockquote>
<pre>
\renewcommand*{\@seccntformat}[1]{%
\csname the#1\endcsname\quad
}
</pre>
</blockquote><p>
Suppose you want to put a stop after every section (subsection,
subsubsection, …) number, a trivial change may be implemented by
simple modification of the command:
<blockquote>
<pre>
\renewcommand*{\@seccntformat}[1]{%
\csname the#1\endcsname.\quad
}
</pre>
</blockquote><p>
However, many people want to modify section numbers, but not
subsection numbers, or any of the others. To do this, one must make
<code>\</code><code>@seccntformat</code> switch according to its argument. The following
technique for doing the job is slightly wasteful, but is efficient
enough for a relatively rare operation:
<blockquote>
<pre>
\renewcommand*{\@seccntformat}[1]{%
\csname the#1\endcsname
\csname adddot@#1\endcsname\quad
}
</pre>
</blockquote><p>
which uses a second-level command to provide the dot, if it has been
defined; otherwise it merely appends <code>\</code><code>relax</code> (which does nothing
in this context). The definition of the second-level command (the
version for the <code>section</code>, here) specifies what to put after a
section number, but it could be used to put anything after it:
<blockquote>
<pre>
\newcommand*{\adddot@section}{.}
</pre>
</blockquote><p>
Note that all the command definitions above are dealing in
<a href="FAQ-atsigns.html">LaTeX internal commands</a>, so the above
code should be in a package file, for preference.
<p/>The <i>Koma-script</i> classes have different commands for specifying
changes to section number presentation: <code>\</code><code>partformat</code>,
<code>\</code><code>chapterformat</code> and <code>\</code><code>othersectionlevelsformat</code>, but otherwise
their facilities are similar to those of “raw” LaTeX.
