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).
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.
