Thanks Doc, I look forward to trying it out.
Rockytime (and others), I hear a lot about apps used on the smart phones and such and I know about programs for the computer (Heck, I spent the last 25 out of the last 30 years as a computer programmer.) I guess my problem with these kind of devices in a shop (mine anyway) is the constant hazards to the devices themselves. Between hot metal flying everywhere, showers of oil and cutting fluids, and metal stock that isn't always placed where it should be I've got to believe that they are "living on borrowed time". If this calculator (which was built with these conditions in mind - one would hope anyway) somehow becomes part of the chip pile I'm only out seventy or so bucks, smart phone maybe three or four hundred. Laptops, of course, up the ante even more.
FWIW :biggrin:
