Comment

Business Rules! lines may include a comment after the statement(s). The comment must be separated from the rest of the statement by at least one space and an exclamation point or the REM statement.

The keywords for comments are:

Rem	Used to comment out a whole line number, or the remainder of a whole line.
!	Used to comment out just one sub-line (see line-continuation), or the remainder of a sub-line. Can be used in a Sort Control File.
Use	Not suggested, but preserved for legacy purposes. It is similar to Rem.
