Editing List of DOS commands (section)

=== REM ===
Remark ([[comment (computer programming)|comment]]) command, normally used within a [[batch file]], and for DR-DOS, PC/MS-DOS 6 and above, in CONFIG.SYS. This command is processed by the command processor. Thus, its output can be redirected to create a zero-byte file. REM is useful in logged sessions or screen-captures. One might add comments by way of labels, usually starting with double-colon (::).   These are not processed by the command processor.
