Parameters
| Parameter | Description |
|---|---|
|
<Comment> |
Specifies a string of characters to include as a comment. |
|
/? |
Displays help at the command prompt. |
Remarks
-
The rem command does not display comments on the screen. You must use the echo on command in your batch or CONFIG.SYS file to display comments on the screen.
-
You cannot use a redirection character (< or >) or pipe (|) in a batch file comment.
-
Although you can use rem without a comment to add vertical spacing to a batch file, you can also use blank lines. Blank lines are ignored when a batch program is processed.
Examples
The following example shows a batch file that uses remarks for comments and for vertical spacing:
| Copy Code | |
|---|---|
@echo off rem This batch program formats and checks new disks. rem It is named Checknew.bat. rem rem echo Insert new disk in Drive B. pause format b: /v chkdsk b: | |
To include an explanatory comment before the prompt command in your CONFIG.SYS file, add the following lines to CONFIG.SYS:
| Copy Code | |
|---|---|
rem Set prompt to indicate current directory prompt $p$g | |
