  Well, not to criticize or anything, but if you're trying to do what I think
you're trying to do, don't. If all you want is to stay inside your repeat, 
fine. If you want to enter your repeat from some line above it, IN THE SAME
MODULE and such that it doesn't exit any loops before they naturally 
terminate, fine. If you want, however, to jump across modules or exit loops
prematurely, then you've missed the whole point of Pascal, and structured
programming. 

  If indeed this *IS* what you want to do, then either restructure your 
program to avoid this odd state of affairs, or take up Basic.
