A comment is a sequence of characters that are ignored when processing a command. A semicolon (not otherwise part of a "string constant") indicates the beginning of a comment.

All characters to the right of the semi-colon are considered comments, and are ignored. Except for percent-signs (%). If you choose to put a comment at the end of a line, that includes a percent sign, you must specify %%.

Blank lines are also ignored.

Examples of comments:

Special note: If you choose to put a comment at the end of a line, that includes a percent sign, you must specify %%.

percent = value * 0.5 ; 50%% of value is
