      I know a guy who has made a living at it for the better part of 30 years. He's now
      working for the main forth guy who has done a whole ASIC company using it. I forget
      the main forth guy's name, but I can find out if you're interested.

      I've not really kept up with the other guy. But whenever one of us hears about the
      other, 3rd party razzing takes place usually about forth or lack thereof.

        That would be much appreciated!

        That's right, it's like Pascal. I remember now. I think I ran across
        it on the Turbocnc list. Turbocnc is written in Pascal. No intent to
        start a flame war!

        Seems like it was hard to find a copy from Borland to compile Turbocnc
        with at the time. I'm used to C, like a pair of old shoes.

        I don't have any experience with Mac or Apple's, and my phone is a very
        simple device. I think I'll stick to some of Microchip's offerings for
        my 'bots.
