This is a polling loop;  you never want one of these under OS/2. The above
code can be compleletely replaced with

       c:=readkey;

If you have work you want to do when a key is not pressed,  use another thread.


The short answer to your question is DosSleep();  but I'd hate for you just
to stick a DosSleep(1) in your original code;   a little redesign will
result in a program that has no polling loops.
