##### 8.5.4.1 Special Characters

The character # is a line comment character. It starts a comment if and only if it is placed at the beginning of a line.

A ; character starts a comment anywhere on the line, causing all characters up to the end of the line to be ignored.

A @ character is handled as a line separator equivalent to a logical new-line character (except in a comment), so separate instructions can be specified on a single line.
