##### 9.4.2.2 Special Characters

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.
