Hi guys;

For those using Linux, (and others if you're enough of a programmer), there's
another option in "bc". Bc is an arbitrary calculator language, and even comes
with an RPN version for Forth and Hewlett-Packard fans. It can do any math
related functions and use the print command to output, for instance, G-code
type text.

I've used it for a unit conversion util I typed in from a give away sample card,
and it's pretty versatile. I have the latest bells and whistles version GNU
Copylefted source if you have the old, somewhat limited posix version.

Bill, would posting my util for folks to try be OT here? It's two text files,
one super short, and the other about as big as some of the bigger posts I've
seen here.

Bill
