Comments

A comment is any line that begins with the comment delimiter. The default comment delimiter is an exclamation mark, `!`. The comment delimiter is controlled by the `COMMENT` characteristic. Comment lines are simply ignored, but can be useful for documenting script files. Comments can also be appended to the end of any line in a script file. Just start the comment with the comment delimiter. For example:

     READ FILE.DAT X Y Z ! this is a comment
