Fair enough, that's a very good question. Now:
Why must the code be included in command.com?
Why must the code not be included in run-time loadable objects?
I don't know if it would work, but I believe the DLM project has
something _similar_ (though it would probably need to be modified to work
in command.com)
I unfortunately can't find the URL right now (sigh :( ),
but someone on this list should have it.
