Rodrigo Murillo asks why the batch-file test if errorlevel N ... succeeds for any errorlevel value that is greater than or equal to N. (Note that this is the documented behavior.) This is something of a philosophical question. I think it most likely that somebody thought they were saving 5 or 6 bytes of code this way. A more forgiving guess might be that someone had a particular style of use or prior example in mind, although my MSDOS manual notes that "Most MS-DOS programs currently return an exit code of 0 at all times." Or perhaps it's best explained in the same way that one explains the rest of MSDOS, and indeed the machines that employ all this mess -- It is the way it is, in order to build the programmer's character.
