First of all many thanks to my wife Tricia who allows me to spend many hours
on my computers.
Also to David Benn and Herbert Breuer for the ACE/AIDE combination supplied
on an AMIGA FORMAT floppy disk which made it easy to compile this program.
And finally to anyone else who I may have neglected or forgotten.
