Contracts are added to our database by going to a dataara and retrieving
the next contract number.
This next contract number is used to add the new contract record.
(contract number is primary unique key).
It is possible that contract numbers already exist sporadically, so
somewhere in the logic the contract file must be checked for key existence.
Is it OK to find the next contract # during the contract add? I would
think that this would be risky and it may be better to simply bump the data
area by 1 and then wait and validate it is unique whenever the NEXT user
tries to add a contact.
