REM

Enables you to include comments in a batch file or in your CONFIG.SYS file.
The REM command - (or double colon (::) in batch files), is also useful for
disabling commands. (You can use a semicolon (;) instead of the REM command
in your \CONFIG.SYS (Win9x \MSDOS.SYS & REG files), 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.
