Hi Folks!
Transaction M900 starts program SBC0900.
Transaction TMDS starts program SBCP785.
Transaction MMCP also starts program SBC785 and MMCP is used by several other programs (in other regions) to run SBCP785. One of these transacation/program is M900/SBC0900.
The program SBC0900 starts TMDS as follows -
EXEC CICS START
TRANSID ('TMDS')
FROM (SBMPF-RECORD)
RESP (CICS-RESPONSE)
END-EXEC
In SBCP785 (attached to TMDS txn), how can I make out whether the program was STARTed by M900/SBC0900 or another transaction/program (perhaps in another region)?
Besides M900/SBC0900, the other programs use the following command to start MMCP/SBCP785 -
EXEC CICS
START TRANSID ('MMCP')
FROM (SBMPF-RECORD)
END-EXEC
Any help most appreciated.
Thanks,

If you are invoking the program SBCP785 using LINK or XCTL then the following command can be used to find out the invoking program name...
EXEC CICS ASSIGN INVOKINGPROG(data-area) END EXEC
| Quote: |
| INVOKINGPROG(data-area) returns the 8-character name of the application program that used the LINK or XCTL command to link or transfer control to the current program. |
If you invoke the program only using START command, I think the only way is to pass the transaction name also along with your other data by adding a member variable in SBMPF-RECORD to have the transaction name.

Thanks Folks!
Dinesh, program SBC0900 invokes SBCP785 by using a START statement.
Passing the value "M900" in a variable defined in SBMPF-RECORD is not an option since the same copybook is used by other transactions besides "M900" to pass information to SBCP785. There is no free variable space available, and if I add a new field to SBCP785, all the other programs would have to be changed too (or atleast recompiled), and these other programs are in other sub-systems which do not belong to our group. The scope just widens up.
Is there another way this can be done?
Any help from anyone greatly appreciated.
Thanks! |

Prince,
Try to utilize the CHANNEL option available with START command to exchange data between two programs. To know more about Channel, take a look at the

| CICS Application Programming Guide |
from ibm.com.
From the invoking program, you can code the following to pass the data
EXEC CICS PUT CONTAINER(container-name1)
CHANNEL(channel-name) FROM(SBMPF-RECORD)
END-EXEC
EXEC CICS PUT CONTAINER(container-name2)
CHANNEL(channel-name) FROM(ws-transaction-name)
END-EXEC
EXEC CICS START TRANS-ID
CHANNEL(channel-name)
END-EXEC
In the started transaction, you can code the following to recieve the data
EXEC CICS GET CONTAINER(container-name1)
CHANNEL(channel-name) INTO(SBMPF-RECORD)
END-EXEC
EXEC CICS GET CONTAINER(container-name2)
CHANNEL(channel-name) INTO(ws-transaction-name)
END-EXEC

This would again require that all the transactions/programs that invoke SBCP785 will have to code their corresponding START statement with the CHANNEL option. As I had mentioned before, there are some programs in other sub-systems (not owned by us) that will also need to be changed, and that option is not available.
If that option was available, simply coding the START command with RTRANSID(M900) and RETRIEVE INTO data-var RTRANSID, would have been enough.
Thanks for your suggestion though. Can you think of anything else?
Thanks,
Prince

Hello,
One way might be to create a new transaction/program for the new requirement. Over time others could be converted to the use new convention. For the initial case you'd have what you need and not be compelled to change and/or re-compile everything.
It would mean dual maintenance for a time, but would avoid the global re-work. The trick would be to get things "converted" sooner rather than later. Often, once the urgency is over, the followup work doesn't happen. . .
Not my preferred way, but sometimes things are such that not everything can be changed at one time. |
