Dear Naidu,

Ok, I am guessing, what you want!

PROGRAM A calls PROGRAM B.

I assume X as the transaction name of A.

So

EXEC CICS XCTL PROGRAM(B) END-EXEC.

The answer to your question, there is no need to create a transaction name for B and the transaction name of A (that's X) will not change.

Are you clear or not?

Hi Mahendar Naidu,

U will have to follow the following steps to run the above program

Define & install prog A
Define & install trans for prog A (for prog B trans is not required)

Thank You,

hi Bramhananda Reddy. K,

ok, i have program A and B.
Program A will do Addition and B will do Subtraction.
In PCT, Prog A tran id X(function name ADD), Prog B tran id Y(SUB).

Now i am calling B from A, so control will trafer to B(permanently), so traction id will change or not?

Thanks,
Naidu

The transaction Id will change. Say currently you are executing tran A, the active transaction would be A. Then you execute an XCTL to tran B then the active transation would be tran B. The whole concept of LINK and XCTL is transferring control and resources to the called program so the active transaction would still be the active program. In this case program B. I hope this helps.

Program A has PPT entry. It also was given a PCT entry of X.
Program B has PPT entry. It also was given a PCT entry of Y.

Now tran X is strated. It starts program A.
Now prog A, XCTLs to prog B.

The transaction ID while executing program B is also X only.

Please write simple program and execute it using CEDF. In the CEDF screen, you can see the program name and transaction ID clearly and you can judge, if the transaction changes are not on your own.
