<a name="index-line-comment-character_002c-M680x0"></a>
<a name="index-comments_002c-M680x0"></a>
<p>Line comments are introduced by the &lsquo;<samp>|</samp>&rsquo; character appearing
anywhere on a line, unless the <samp>--bitwise-or</samp> command line option
has been specified.
</p>
<p>An asterisk (&lsquo;<samp>*</samp>&rsquo;) as the first character on a line marks the
start of a line comment as well.
</p>
<a name="index-M680x0-immediate-character"></a>
<a name="index-immediate-character_002c-M680x0"></a>
<p>A hash character (&lsquo;<samp>#</samp>&rsquo;) as the first character on a line also
marks the start of a line comment, but in this case it could 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>). If the hash character
appears elsewhere on a line it is used to introduce an immediate
value. (This is for compatibility with Sun&rsquo;s assembler).
</p>
<a name="index-M680x0-line-separator"></a>
<a name="index-line-separator_002c-M680x0"></a>
<p>Multiple statements on the same line can appear if they are separated
by the &lsquo;<samp>;</samp>&rsquo; character.
