Optional DCT Entries

Specify a value for the DESTID parameter in the EBCXMOPT macro in the EC0XMCTR module and corresponding DCT entries. This value defines a transient data destination for messages issued by the subtask.

Note: Specify a blank for DESTID to suppress the generation of informational messages from the subtask.

The DCT entries for a DESTID of XMC0 are:

RMOLOG   DFHDCT TYPE=SDSCI,   FOR CICS MESSAGES AND SHUTDOWN
               BLKSIZE=250,   STATISTICS
               BUFNO=1,
               DSCNAME=RMOLOG,
               RECFORM=VARUNBM,
               RECSIZE=242,
               TYPEFLE=OUTPUT
XMC0G    DFHDCT TYPE=EXTRA,
               DESTID=XMC0,
               DSCNAME=RMOLOG

Step 3: (Optional) Invoke the System from a CICS Menu System

If you want to invoke CA Deliver from a user-written CICS menu system, then return to that menu system when you exit from CA Deliver, do the following:

Invoke CA Deliver from the menu system by using this CICS command:

EXEC CICS START TRANSID(DELIVER transaction-id)
     TERMID(EIBTRMID)
     FROM(data-area)
     LENGTH(4)

where:

TRANSID(DELIVER transaction-id)

Specifies the CA Deliver transaction ID.

TERMID(EIBTRMID)

Specifies the terminal that a CA Deliver transaction will communicate with.

FROM (data-area)

Specifies the optional variable length character string.

The format of the data-area parameter is:

tran,

where:

tran

Specifies the return menu CICS transaction to be started when CA Deliver finishes.

Note: None of the data-area parameters is required.

LENGTH (4)

Specifies the number of bytes in the data field being passed.

Note:

When CA Deliver receives control, it retrieves the four-byte return transaction ID and saves it from iteration to iteration.

If the retrieve fails, CA Deliver retains the information that it was started directly from a terminal, not a menu system.

When CA Deliver finishes processing, it determines whether it should return to a menu system by starting the return transaction.

If there is a saved transaction ID, CA Deliver starts the return transaction before it exits to CICS by issuing:

EXEC CICS START TRANSID(RETURN transaction-id)
     TERMID(EIBTRMID)
     NOCHECK

CICS Notes

The cross memory CICS access involves two different address spaces: the CICS address spaces and the XMS address spaces.

CICS Address Spaces

The user's CICS transactions and the cross memory support subtask reside in the address spaces.
