##### 9.47.2.1 Special Characters

``#`' is the line comment character. If a ``#`' appears as the first character of a line, the whole line is treated as a comment, but in this case the line can also be a logical line number directive (see Comments) or a preprocessor control command (see Preprocessing).

Two dashes (``--`') can also be used to start a line comment.

The ``;`' character can be used to separate statements on the same line.
