Hide REM lines from showing in a batch file

The REM command only remarks the line from being executed. However, if @echo off is not in the batch file that line still echos to the screen. To prevent these lines from being shown, you can do one of three things.

Add @echo off to the batch file

To hide all commands and the REM lines add @echo off as the first line in the batch file.

Change the REM to @REM

To have the commands shown when the batch file is run, but still want to hide the REM lines type @REM instead of REM.

Use :: instead of REM

Finally, using the :: as the remark command instead of REM also prevents the echo of the remarked line.
