[comp.os.msdos.programmer] Breaking out of reads with the clock interrupt

georges@earthquake.Berkeley.EDU (Christopher Georges) (03/12/91)

I have an on-screen clock that is visible while the user is typing input.
What I'd like to do is when the clock reaches a certain point, if the user
has not completed typing I want to use the clock interrupt to break out of
the read call  (It's a readln call in Turbo Pascal if that makes any 
difference) and continue my program.  Is this possible without screwing
everything up, and if so, how?   Any help would be greatly appreciated.

Thanks,
chris
