Retrieving unsolicited messages

After you set up the environment with CSLULXSB, you can use the CSLULSUB, CSLULUSB, and CSLULGUM functions to subscribe to OM for unsolicited output messages.

CSLULSUB request
By issuing the CSLULSUB request, you can start the subscription and monitor OM for unsolicited messages.
CSLULUSB request
By issuing the CSLULUSB request you can end the subscription. If a subscription does not exist, OM is no longer monitored for unsolicited messages.
CSLULGUM request
By issuing the CSLULGUM request you can copy unsolicited output messages to the REXX program variable named stem_name. The REXX program can then examine the messages and take appropriate action.
Sample program for subscribing to OM
This REXX SPOC API sample program uses CSLULSUB, CSLULBGUM, and CSLULUSB to subscribe to OM and to retrieve unsolicited messages. The program shows how you can invoke unsolicited output message functions.
