Are you sure about that? The source I assembled it from was written to
delay for 182 ticks. Oh, well - no biggie. Did you try running it at,
say, 5 seconds before midnight under DOS? If you did, and it didn't
abort at midnight, could you please tell me which version of DOS, and
if you've loaded any drivers, TSRs, etc. that hook any of the timer/
clock ints./routines?

I tried both of these methods - it still aborted at midnight (but not
at the changing of the hour (?)).

I'll give this a try (even though it multitasks quite well here under
both Desqview 2.63 and Windows 3.1).

Yes, it does - and I appreciate your help.
