Open ClientConnect communicates message text to the CSA using the SPMSG field. In the sample program, issuing the GETMSG command retrieves the message text from SPMSG; the messages are then written to temporary storage:
CALL 'GETMSG' USING SPAREA
IF SPMSG NOT = SPACES
EXEC CICS
WRITEQ TS QUEUE('CSEXQUE')
FROM(SPMSG) NOSUSPEND
RESP(CICSRC)
END-EXEC
END-IF.
See Appendix A, “CSA Commands” for details about the MESSAGE command and Appendix E, “The SPAREA” for information about the SPAREA.
