Control-O/CICS Interface

Although regular Control‑O processing can handle CICS messages that are sent to the MVS console, most CICS messages are not sent to the MVS console. CICS sends messages to an internal component called the Transient Data Queue and sometimes to the user console as well.

The Control‑O/CICS interface enables you to retrieve these messages.

Note: CICS commands are executed in a CICS transaction. There is no CICS exit that handles CICS system commands. Therefore, the Control‑O CICS interface cannot handle CICS system commands.
