Many years ago I went to single record control files by application.
For example, I have a billing control file with a single record that
INVMS Invoice Message 84 A
SVCLM1 Service Charge Limit #1 7,2 P
SVCAM1 Service Charge Amount #1 5,2 P
SVCLM2 Service Charge Limit #2 7,2 P
SVCAM2 Service Charge Amount #2 5,2 P
SVCLM3 Service Charge Limit #3 7,2 P
SVCAM3 Service Charge Amount #3 5,2 P
SVCLM4 Service Charge Limit #4 7,2 P
SVCAM4 Service Charge Amount #4 5,2 P
SVCLM5 Service Charge Limit #5 7,2 P
SVCAM5 Service Charge Amount #5 5,2 P
SVCCHGDS Service Charge Description 50 A
DATE1 Billing Date *ISO
LSTIN Last Invoice Number 7,0 P
DAY Billing Day 1,0 S
LSTOR Last Order Number 7,0 P
LSTCB Last Consolidated Billing 7,0 P
LSTAK Last OW Acknowledge Number 5,0 P
FSCAM Fuel Surcharge Amount 5,2 P
FSCDS Fuel Surcharge Description 50 A
Other applications like receivables, payables, etc have similar single
record control files.
I just felt better putting this stuff in a DB file instead of a data area.

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.
