REM
[/?]
[anything]
/?The REM command ignores its arguments and does nothing (except for when printing on-line help in response to the /? option). It is used for "remarks" in command scripts.
Note: Because REM is a command, redirection still occurs, and command separator characters will be respected and will start a new command. To create a remark where redirection does not occur, and command separator characters are ignored, use the double colon instead. This does not match the behaviour of the 16-bit CMD supplied with IBM OS/2, which ignores rediection for REM commands. But it does match that of the original COMMAND supplied with OS/2 and with DOS, and is also consistent with the way that all other commands work.
