<a name="index-i386-line-comment-character"></a>
<p>The presence of a ‘<samp>#</samp>’ appearing anywhere on a line indicates the
start of a comment that extends to the end of that line.
</p>
<p>If a ‘<samp>#</samp>’ appears as the first character of a line then the whole
line is treated as a comment, but in this case the line can also be a
logical line number directive (see <a href="Comments.html#Comments">Comments</a>) or a preprocessor
control command (see <a href="Preprocessing.html#Preprocessing">Preprocessing</a>).
</p>
<p>If the <samp>--divide</samp> command-line option has not been specified
then the ‘<samp>/</samp>’ character appearing anywhere on a line also
introduces a line comment.

<p>The ‘<samp>;</samp>’ character can be used to separate statements on the same
line.
