9.44.12.1 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 (Comments) or a preprocessor control
command (Preprocessing).
The presence of an asterisk ('*') at the start of a line also
indicates a comment that extends to the end of that line.
The TIC54X assembler does not currently support a line separator
character.
