One solution is to simply check if the TIMER seconds changed and just
increment a counter. It's a little choppy if one needs fine resolution
but it sidesteps the midnight problem. Otherwise one might use the
number of seconds in a day idea i.e. 86400 seconds / 24 hours:

     SUB Delay (t%)

        StopTime& = TIMER + t%
        DO
           IF LEN(INKEY$) THEN EXIT DO
        LOOP UNTIL (StopTime& - TIMER) MOD 86400 <= 0

     END SUB
(An alternative to checking INKEY$ is to give up the time slice
i.e. increment an elapsed time bargraph or show an hourglass [blech!])

One may also check the bios "midnight" bit and add 86400 but why bother.
