 Comment statements begin with two forward slashes “//” and finish at

the end of the line.

 A comment may contain any character. It may be on a line by itself,

or after a label or command statement.

creating white space.

Examples:

// The entire line is a comment.

IF $MsgText == “ERROR” //comment after a command
