  • INP(&H60)

    The INKEY$ topic is quite informative. I'm wondering if INP(&H60) has the same effect on the CPU as does a tight INKEY$ loop?

    It is the tight loop without releasing time-slices to the O/S, rather than the specific statements inside the loop. Try it out for yourself...

      Thanks, Lance.

      I'd try it myself, but I don't have all the toys other folks have. If I did, I would not have asked the question in the first place.

        I don't know if this will help but if you have any documentation
        that explains DOS interrupts, you may want to take a look at
        int16h sub-functions 11h and 10h (in that order).

        11h looks at the keyboard buffer, returns a result and moves on.

        12h will remove a keystroke if it is available. If not available
        it will freeze until one becomes available.

          Sorry but the last paragraph should start with 10h instead of 12h
          My appologies.
