Control-O Interface for the CICS Environment

The Control‑O/CICS interface uses the CICS XTDOUT exit to intercept CICS messages that are to be sent to the Transient Data Queue. This exit receives control before each message is written to the Transient Data Queue and passes it to the Control‑O/CICS interface module CTOCTDX. Module CTOCTDX passes the message to the Control‑O WTO executor module (CTOWTO) as a WTO message. Module CTOWTO determines whether the message must be untouched, changed, or suppressed (that is, not written to the Transient Data Queue).
