##### 9.25.3.1 Special Characters

The characters ‘`*`’ and ‘`#`’ are line comment characters; each start a comment at the beginning of a line, but only at the beginning of a line. A ‘`#`’ prefixes a hexadecimal number if found elsewhere on a line.

Two other characters, ‘`%`’ and ‘`!`’, each start a comment anywhere on the line. Thus you can't use the ‘`modulus`’ and ‘`not`’ operators in expressions normally associated with these two characters.

A ‘`;`’ is a line separator, treated as a new-line, so separate instructions can be specified on a single line.
