? Using the echo command to display annotations
The REM command does not display annotations on the screen. You must use the Echoon command in a batch or Config.nt file to display annotations on the screen.
? Restrictions on comment on batch files
You cannot use the redirection character "(" or ")" or the Pipeline (|) In a batch file comment.
