I am looking for a way to find out calling program name while control
is in the called program in batch mode.

Is this a one time deal, or is it a necessity for every calling module during your batch run? Adding a parm to pass the callers name could be one way to go about this, or, to find out who is calling the module in a specific situation, force the module to abend and look at the calling chain in the dump.
May need a little more information to go on in order to provide better help. Thanks,

I need to identify calling program name each time it calls the submodule, something
similar to CICS command ASSIGN INVOKINGPROG (XXXXXXXX). Passing a parm
from calling program is not an option.
Thank you.

Hi Viz,
If you want to code this feature into your subpgm you'll have to access system control blocks, and this will depend on what your hardware/software configuration is and, most importantly, what COBOL compiler/version you're using.
If you have the flexibility to do it, Greenguy's suggestion of passing the pgm name is the simplest solution.
Good Luck, Jack.

Hi Viz,
Your reply slipped in before I sent my post. It sounds like you're running in a mainframe environment. Does the compiler you're using support the PROCEDURE POINTER facility? Let me know; if it does there should be a relatively simple solution.

Jack,
Yes, our compiler supports procedure pointer facility.
Yes, our compiler supports procedure pointer facility.
Hi Vis,
Couldn't sleep, so I thought I'd give this a go.
OK, you want to get the caller's pgm name.
One caveat before I start: this hasn't been tested, but it should work. I'll give you a plain English overview (well English anyway) and then a sort of pseudo pseudo code. If you have any ques, you know where I live.
The initialization code of a cobol pgm contains, among other things, its pgm name and its TGT address. The first 72 bytes of the TGT contain the register save area for the pgm. You want the pgm name of your caller, so we have to back chain to your caller’s caller register save area (in most cases an MVS module). Then we can use the register 15 save to get the entry point address of your caller. Five bytes from there is the 8 byte pgm name you’re looking for. That's for COBOLII, for VS/COBOL its 12 bytes. Now for the code.
As the song goes Oops, there it is. I've got a pgm that bounces around The MVS control blocks that may help in understanding the pointer facility and how it can be used to find system data. If you want it send me your e-mail addr. And remember, when going thru the code above, it's 5AM.
Good luck, Jack.

I left out a statement that should go after the "set procedure pointer" statement. I'm enclosing the rewritten code below. I warned you it was 5AM.

Jack,
As far as providing the code goes, I am using exactly what you gave above. I set up a five level call chain of programs that do nothing more than display their name and call the next one....until I get to the 5th module. That is where I plugged your exact code in and am trying to get my back chain of programs to be displayed.
I set up this simple test scenario to see if I could in fact get your code to work, and if so, I will use it to solve an existing business problem. The errors from my compiler are given below:
The only change that I made to your code was to insert "cobol5" where you had "mypgmnm", and displaying the callers program name rather than moving it to a hold field.
Thanks again for your time. Thanks,
s-)

Hi GG,
Didn't notice this in your previous post. COBOLII doesn't support procedure pointers. I know LE/COBOL for MVS and VM
(they keep changing the name of COBOL/370) supports it. You
might check w/your sysprogs; they may have it laying around,
IBM is dropping COBOLII support very soon. Thanx for finding that error of mine though.
Thanx, Jack.
P.S. Don't worry about bothering me; whatever it takes.

Hi GG,
I'm enclosing some code I used to provide run info
in a VSCOBOL/COBOLII environment.
Look at the code commented:
*===> SET UP PGM NAME FOR DISPLAY
If you eliminate the PERFORM and execute
SET ADDRESS OF LK-CDE TO LK-PREV-CDE-ADDR
only once, I think that will give you the pgm name
of the caller.
Scan the code and decide what parts of it you need
to get to the caller's pgm name.
You might want to test both a static and a dynamic
call to your pgm. I was using a static call.
Hope this helps, Jack.
P.S. Let me know how you make out. Code follows.

Thanks Jack! At long last I was able to get some sort of output......although, the manner in which you got to it still has me chasing my tail a little.
I displayed the program name inside of your perform varying loop and was able to come up with a chain of load modules. Where it goes from here is up to someone else........finally out of my hands!
Thanks again, that's a slick chunk of code.
Jeff Thanks,

Hi GG,
Just a final caveat about the code. Since a lot of the code is assuming a predefined construct for certain OS cntl blocks, if that changes the code will go haywire. On the otherhand, these cntl blocks are fairly mature and shouldn't change (famous last words).
