Explicit DB-Access Transactions
When you use DB-Access in interactive mode with a database that is not
ANSI-compliant but that supports transaction logging, if you select the Commit menu but do not issue the COMMIT WORK statement after
a transaction has been started by the BEGIN WORK statement, DB-Access automatically
commits the data, but issues the following warning:
Warning: Data commit is a result of unhandled exception in TXN PROC/FUNC
The purpose of this warning is to remind you to issue COMMIT WORK explicitly to end a transaction that BEGIN WORK initiated.
In non-interactive mode, however, DB-Access rolls back the current transaction if you end a session without issuing the COMMIT WORK statement.
