    I find the Inplace Operations "PRE_RANDOM" and "POST_RANDOM" very interesting... (hmmm)

    SPIN uses a 32bit LSFR with 4 taps with random. I didn't really know what to call them. I guess it should have been FORWARD_RANDOM and BACKWARD_RANDOM.


    And as far as Z80 based machines go... I own a Genesis (audio co), Sega master system, timex sinclair 1000, sinclair ZX81, Every ideration of the gameboy except the light (even though the gameboy didn't use a Z80, it used a near compatible), Game gear, and my Apple IIe had some weird co-processor Z80 card in it when I was growing up... I think that about covers it.

    Never did the CP/M. I was a commodore guy.

    I didn't know spin had a RANDOM operater until now.
    I looked in the book and there it was. (lol)
    Everyone!! The Question Mark Symbol is used for random.
