Would it be the Texas Instruments calculators, Joseph? I've seen your
posts in bit.listserv.calc-ti. Certainly a compiled high-level language,
C or Pascal, say, would be a mighty improvement on TI-Basic for
programming the calcs.

        I posted here (c.o.cpm) a while ago (April) asking for
information from the CP/M gurus on this subject.

Anybody else have an opinion?

I've cross-posted back to bit.listserv.calc-ti, as it seems to me that
some cross-fertilisation on these ideas might pay off.
