(* I'm still learning Modula-2 and programming on Amy, so this may not
be the tidiest or best way to do what the program does. Also, it is
probably not the most elegant example of structured programming ever
created. Finally, I am certain that there are many enhancements that
more experienced programmers will be able to add (like maybe a close
gadget and the wherewithall to respond to it). Please fiddle at will. If you have comments or suggestions, please contact me on PeopleLink or by U.S. Snail at:

Thanks in advance. *)
