##### 9.27.1.1 Special Characters

The presence of a ‘`#`’ appearing anywhere on a line indicates the start of a comment that extends to the end of that line.

If a ‘`#`’ 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 Comments) or a preprocessor control command (see Preprocessing).

If Sequent compatibility has been configured into the assembler then the ‘`|`’ character appearing as the first character on a line will also indicate the start of a line comment.

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