The presence of a ‘@’ 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 could also be a logical line number directive (see Comments) or a preprocessor control command (see Preprocessing).
The ‘;’ character can be used instead of a newline to separate statements.
Either ‘#’ or ‘$’ can be used to indicate immediate operands.
*TODO* Explain about /data modifier on symbols.
