comment

Descriptive information put in a source file to explain the files contents. Comments are introduced with special symbols to notify the compiler that subsequent text can be ignored. In 4GL source modules, comments can be introduced by putting the left brace ( { ) in the first position of the source file line to open a comment. You must then also include a right brace ( } ) anywhere on a line to close the comment. To put a comment on the same line as code, precede the comment with a double-hyphen ( -- ) or the # symbol. In 4GL form specification files, comments can be introduced with braces and the double-hyphen; the initial # symbol is not valid.
