<p>The presence of a ‘<samp>@</samp>’ 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 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>The ‘<samp>;</samp>’ character can be used instead of a newline to separate

statements.
