CIUOW (10-digit signed integer)

Unit-of-work control.

This controls the unit-of-work processing performed by the CICS bridge. We can request the bridge to run a single transaction, or one or more programs within a unit of work. The field indicates whether the CICS bridge should start a unit of work, perform the requested function within the current unit of work, or end the unit of work by committing it or backing it out. Various combinations are supported, to optimize the data transmission flows.

The value must be one of the following:

CUONLY

Start unit of work, perform function, then commit the unit of work (DPL and 3270).

CUCONT

Additional data for the current unit of work (3270 only).

CUFRST

Start unit of work and perform function (DPL only).

CUMIDL

Perform function within current unit of work (DPL only).

CULAST

Perform function, then commit the unit of work (DPL only).

CUCMIT

Commit the unit of work (DPL only).

CUBACK

Back out the unit of work (DPL only).

This is a request field. The initial value of this field is CUONLY.
