The original question was on how to break out of a SLEEP.  Several people,
including myself, suggested using shorter SLEEPs, along with INKEY, to be
able to cancel the sleeping.

Yes, the use of INKEY in a busy-loop is a CPU hog.  However, by using it
along with SLEEP, you have eliminated that issue.
