                                    REM

Enables you to include comments in a batch file or in your CONFIG.SYS file.
The REM command is also useful for disabling commands. (You can use a
semicolon (;) instead of the REM command in your CONFIG.SYS file, but not in
batch files.)

Syntax

    REM [string]

Parameters

string
    Specifies any string of characters -- the command you want to disable or
    the comment you want to include.

Related Command

For information about displaying messages, see the <ECHO> command.

                                 REM--Notes

Using the ECHO command to display comments

The REM command does not display comments on the screen. You must use the
ECHO ON command in your batch or CONFIG.SYS file in order to display
comments on the screen.

Restrictions on characters in batch-file comments

You cannot use a redirection character (> or <) or pipe (|) in a batch-file
comment.

Using REM to add vertical spacing

Although you can use REM without a comment to add vertical spacing to a
batch file, you can also use blank lines. MS-DOS ignores the blank lines
when processing the batch program.

                                      ***

                               REM--Examples

The following example shows a batch file that uses remarks for both
explanations and vertical spacing:

    @echo off
    rem  This batch program formats and checks new disks.
    rem  It is named CHECKNEW.BAT.
    rem
    echo Insert new disk in drive B.
    pause
    format b: /v
    chkdsk b:

Suppose you want to include in your CONFIG.SYS file an explanatory comment
before the COUNTRY command. To do this, add the following lines to
CONFIG.SYS:

    rem Set country code to France
    country=033

The following example shows a DEVICE command that has been disabled by using
a semicolon (;) instead of the REM command:

    ;device=c:\dos\ramdrive.sys

                                      ***
