From: Nathan Andelin

One big issue, is that RPG can only maintain one record lock
per file. What happens if you're updating multiple records in
the same file?

A good example of this is the banking transaction where the customer
deposits one check, but splits the deposit between more than one account.

Why do you need to lock ALL of the records for the duration of the
transaction? You simply lock each record as you process it.
