RE: Hex in RPG

["Bob Cozzi \(RPGIV\)" <cozzi@xxxxxxxxx>]

There are two solutions, and RPG solution that uses an MI instruction to
convert data to hex, something like this unfinished thing I just hacked
together (see below)... and a much simpler solution which I'm testing at
the moment... I'll post it if it works but it should be only one line of
Calc's and a prototype if it works.
