NOTE

If this is a dynamic transaction, a call to DBXUNDO must be processed if an

error occurs or if the transaction needs to be rolled back for any other reason.

TurboIMAGE/XL will not go on to the next transaction in the event of a

transaction abort unless an intervening call to DBXUNDO occurs.

11.If the status code is zero and this is a logical transaction, call DBEND or, alternatively,

DBXEND to declare the end of the modiﬁcations. However, if this is a dynamic

transaction and DBXUNDO was used to roll back the transaction, your program logic

should ensure that the subsequent call to DBXEND is not processed.

12.Call DBUNLOCK to release all of the locks.
