Caller program from Callee program

Hi All
Is there any way by which I can find the caller program name from the Callee program

For E.g.
If program A is calling program B.
Is there by any chance I can know the program which is calling B . Keeping a break point at B ?

I hope I am clear

Should we assume Xpediter since you're in the Compuware forum -- even though you didn't tell us little details like the tool, the language of the calling program, the language of the called program, and what you've already tried that hasn't worked? Have you tried Xpediter option 2.6.1? The Xpediter COBOL User's Guide talks about returning to the calling program -- read chapters 5.1 and 5.3 for more details.

there is also the simple fact that if pgm b has been CALLed,
how did the TS/OP invoke this CALL?

I am Sorry for missing out on details..

You are correct .. I am using Xpediter to debug programs .. Both programs are in Cobol .. Forther it's an online program
It would be great if you could give me the link of COBOL User's Guide (Xpediter option 2.6.1)

The problem is that I am able to figure out that the control is going to B ..when I set a break point the flow halts at program B ... But I need to find which program is calling B ..

Hi,

So your are using Xpediter/CICS. Once you have stopped at a breakpoint you want to identify the calling program.

I would suggest you activate Xpediter's Trace function - this is option 1.4 from the primary menu.

Then set your breakpoint in the called program.

Then clear the screen and run your test. Once you stop at your breakpoint, look at the trace output - this is option 2.4 from the primary menu. This will give you a statement trace across all programs that were executed. Here you should see the calling program. NOTE: The trace will only record programs and statements for programs are available in the DDIO file. If you don't have a compile listing for a program, it will NOT appear in the trace.

Cheers.

Sam

Hello,

I'm assuming you are accessing the sub-program via a CALL USING from the CALLER and NOT an EXEC CICS LINK?

Sometimes these terms are used synonymously and just wanted make sure.

SET TRACE ON will turn program tracing on.

Using option 0.1 you can see what is all set.

Also, it is NOT TRUE that you need a DDIO listing available for the programs to show up in the trace. Without the DDIO, you will not see the lines of code executed along the way, but you will still see the names of the programs that were executed.
