This sub stops the program by the given amount of seconds with a precision of about 1/15th of second. Note that the TIMER function will reset after midnight; if that's the case, internally the routine will substract 86400 seconds (a whole day) to keep things OK.
SUB Delaysecs (secs!)
Now! = TIMER
o! = TIMER + secs!
DO WHILE TIMER < o!
IF Now! > TIMER THEN o! = o! - 86400
