The numbering system is more complex than just assigning a number. It
invloves about thirty procedures which I have put together and find that it
works well.
I would like to keep the numbering as a database system which will be
possible if I can figure out a way of generating sequential numbers without
possibility of a gap.
Perhaps a manually built table is the answer??
