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.
