Perhaps even a Stretch. A KDF9, maybe, but Stretch? You'd have to be seriously masochistic, or downright insane :-) Cheers, Mike. --------------------------------------------------------------- Mike Hore mike_horeREM(a)OVE.invalid.aapt.net.au ---------------------------------------------------------------

If you want funtional equivalence to the KDF-9 instruction set, then get yourself a copy of the Forth language.
