<H3 CLASS="subsection"><A NAME="toc53"></A><A NAME="htoc70">B.4.1</A>  <A NAME="section:section"></A>Sectioning Commands</H3><P>
Sectioning commands from <CODE>\part</CODE> down to
<CODE>\subparagraph</CODE> are defined in base style files.
They accept an optional argument and have starred versions.</P><P>The non-starred sectioning commands from <CODE>\part</CODE> down to
<CODE>\subsubsection</CODE> show section numbers in sectional unit headings,
provided their <I>level</I> is greater than or equal to the current
value of the <CODE>secnumdepth</CODE> counter.
Sectional unit levels and the default value of the <CODE>secnumdepth</CODE> counter
are the same as in L<sup>A</sup>T<sub>E</sub>X.
Furthermore, given a sectional unit <I>secname</I>, the
counter <I>secname</I> exists and the appearance of sectional units
numbers can be changed by redefining <CODE>\the</CODE><I>secname</I>.
For instance, the following redefinition turn the numbering of
chapters into alphabetic (uppercase) style:
</P><PRE CLASS="verbatim">\renewcommand{\thechapter}{\Alph{chapter}}
</PRE><P>When jumping to anchors, browsers put the targeted line on top
of display. As a consequence, in the following code:
</P><PRE CLASS="verbatim">\section{A section}
\label{section:section}
...
See Section~\ref{section:section}
</PRE><P>Clicking on the link produced by
<CODE>\ref{section:section}</CODE> will result in <EM>not</EM> displaying the
targeted section title.
A fix is writing:
</P><PRE CLASS="verbatim">\section{\label{section:section}A section}
...
See Section~\ref{section:section}
</PRE><P>Note that <CODE>\label</CODE> should not be be placed last in
section title (and I do not know the reason why).
Have a try for this section <A HREF="#section:section">B.4.1</A>!</P><H3 CLASS="subsection"><A NAME="toc54"></A><A NAME="htoc71">B.4.2</A>  The Appendix</H3><P>
The <CODE>\appendix</CODE> command exists and should work as in L<sup>A</sup>T<sub>E</sub>X.</P><H3 CLASS="subsection"><A NAME="toc55"></A><A NAME="htoc72">B.4.3</A>  Table of Contents</H3><P>
<A NAME="@default154"></A><A NAME="@default155"></A>H<FONT SIZE=2><sup>E</sup></FONT>V<FONT SIZE=2><sup>E</sup></FONT>A now generates a table of contents, using a procedure similar
to the one of L<sup>A</sup>T<sub>E</sub>X(a <TT>.htoc</TT> file is involved).
One inserts this table of contents in the main document by issuing
the command <CODE>\tableofcontents</CODE>.
Table of contents is controlled by the counter <CODE>tocdepth</CODE>.
By default, the table of contents shows sectioning units down to the
subsubsection level in <I>article</I> style and down to the subsection level
in <I>book</I> (or <I>report</I>) style. To include more or less
sectioning units in the
table of contents, one should increase or decrease the <CODE>tocdepth</CODE>
counter.
It is important to notice that H<FONT SIZE=2><sup>E</sup></FONT>V<FONT SIZE=2><sup>E</sup></FONT>A produces such a table of
contents, only when it has total control over cross-references.
More precisely, H<FONT SIZE=2><sup>E</sup></FONT>V<FONT SIZE=2><sup>E</sup></FONT>A cannot produce the table of contents when it
reads L<sup>A</sup>T<sub>E</sub>X-produced <TT>.aux</TT> files.
Instead, it should read its own <TT>.haux</TT> files.
This will naturally occur if no <TT>.aux</TT> files are present,
otherwise these <TT>.aux</TT> files should be deleted, or H<FONT SIZE=2><sup>E</sup></FONT>V<FONT SIZE=2><sup>E</sup></FONT>A
should be instructed not to read them with the command-line option
<A NAME="@default156"></A><TT>-fix</TT>
(see Sections <A HREF="manual033.html#files">B.11.1</A> and  <A HREF="manual041.html#heveaoptions">C.1.1.4</A>).</P><P>One can also add extra entries in the table of contents by using
the command <CODE>\addcontentslines</CODE>, in a way similar
to L<sup>A</sup>T<sub>E</sub>X homonymous command.
However, hyperlinks need to be introduced explicitly,
as in the following example, where
an anchor is defined in the section title and referred to in the
argument to <CODE>\addcontentsline</CODE>:
</P><PRE CLASS="verbatim">\subsection*{\aname{no:number}{Use \hacha{}}}
\addcontentsline{toc}{subsection}{\ahrefloc{no:number}{Use \hacha{}}}
</PRE><P>(See Section <A HREF="manual018.html#hyperlink">8.1.1</A> for details on commands related to hyperlinks.)</P><P>There is no list of figures nor list of tables.</P><H3 CLASS="subsection"><A NAME="toc56"></A><A NAME="no:number">Use H<FONT SIZE=2><sup>A</sup></FONT>C<FONT SIZE=2><sup>H</sup></FONT>A</A></H3><P>
However, H<FONT SIZE=2><sup>E</sup></FONT>V<FONT SIZE=2><sup>E</sup></FONT>A has a more sophisticated way of producing
a kind of map w.r.t. the sectioning of the document.
A later run of H<FONT SIZE=2><sup>A</sup></FONT>C<FONT SIZE=2><sup>H</sup></FONT>A on H<FONT SIZE=2><sup>E</sup></FONT>V<FONT SIZE=2><sup>E</sup></FONT>A output file splits it
in smaller files organized in a tree whose nodes are tables of
links.
By contrast with L<sup>A</sup>T<sub>E</sub>X, starred sectioning commands generate
entries in these tables of contents.
Table of contents entries hold the optional argument to sectioning
commands or their argument when there is no optional
argument. Section <A HREF="cutname.html#hacha">7</A> explains how to
control H<FONT SIZE=2><sup>A</sup></FONT>C<FONT SIZE=2><sup>H</sup></FONT>A.</P><HR>
