What you'll want to do is add a delay. Under Virtual Pascal, it uses
DosSleep (under the new version of Virtual Pascal, I beleive it's
something like SysSleep). But Delay should be adequate.

Try;

Repeat
  Do_Something else Delay(1);
until keypressed or ....

That should free some of your CPU cycles for you. Absolutely amazing
what a difference that delay statement works. While testing it out, I
created a program that was basically as you say above (repeat..until
keypressed) and the CPU was pegged at 100%. With the delay in there, it
dropped back down.

Play with the length of the delay and see what gets you the best
results. With DosSleep (VP) I found 1 to work the best. I think with
Delay (BP/TP), 2 was the magic number.
