1 The characters '*' and '#' are line comment characters; each start a
1 comment at the beginning of a line, but only at the beginning of a line.
1 A '#' prefixes a hexadecimal number if found elsewhere on a line.  If a
1 '#' appears at the start of a line the whole line is treated as a
1 comment, but the line can also act as a logical line number directive
DONTPRINTYET 1 (⇒Comments) or a preprocessor control command (*note1DONTPRINTYET 1 (⇒Comments) or a preprocessor control command (⇒
 Preprocessing).
1 
1    Two other characters, '%' and '!', each start a comment anywhere on
1 the line.  Thus you can't use the 'modulus' and 'not' operators in
1 expressions normally associated with these two characters.
1 
1    A ';' is a line separator, treated as a new-line, so separate
1 instructions can be specified on a single line.
