I’ve been writing some batch files, and I ran into this user guide, which has been quite informative. One thing it showed me was that lines can be commented not just with REM, but also with ::. It says:
Comments in batch code can be made by using a double-colon, this is better than using the REM command because labels are processed before redirection symbols.
::<remark>causes no problems butrem <remark>produces errors.
Why then, do most guides and examples I see use the REM command? Does :: work on all versions of Windows?
