<a name="index-line-comment-character_002c-SH"></a>
<a name="index-SH-line-comment-character"></a>
<p>&lsquo;<samp>!</samp>&rsquo; is the line comment character.

<a name="index-line-separator_002c-SH"></a>
<a name="index-statement-separator_002c-SH"></a>
<a name="index-SH-line-separator"></a>
<p>You can use &lsquo;<samp>;</samp>&rsquo; instead of a newline to separate statements.
</p>
<p>If a &lsquo;<samp>#</samp>&rsquo; appears as the first character of a line then the whole
line is treated as a comment, but in this case the line 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>).
</p>
<a name="index-symbol-names_002c-_0024-in-3"></a>
<a name="index-_0024-in-symbol-names-3"></a>
<p>Since &lsquo;<samp>$</samp>&rsquo; has no special meaning, you may use it in symbol names.
