	I advise not doing this if you don't have to.  The main reason is that
you're HIGHLY likely to break in 2.0.  Even Bill Hawes has had a few problems
with this, and he knows dos really well.  If you must do this, use the
arp.library, which will work much better, and when the 2.0 update comes out
arp will probably call the new System() call directly.

	It's not real simple, and anything I tell you is likely to trip you
up in the future.  Manx fexec makes it even more complicated.  The real
solution is in 2.0 (System()).
