Technically, REM is a regular DOS command just like the others -- it's not a "comment" like we're used to seeing in most coding languages. If you type "REM" at a command line it doesn't give you a "Bad Command" error message because it is a legitimate command even though it doesn't really do anything.
The main time this matters is for redirection -- you can redirect the input or output of a REM command. While redirecting the input is pretty pointless, redirecting the output can be a very useful thing to do. You can create a file of zero length (the only space it takes on disk is in the FAT and does not actually occupy any sectors) by doing something like: REM > NADA.BAT This creates a batch file called NADA.BAT that doesn't do anything, but also doesn't use any disk space. Just like the NUL device is handy (and at times even necessary), batch files that don't do anything are sometimes useful as well. _______________________________________________ Freedos-devel mailing list Freedos-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freedos-devel
