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.
