Re: CEETBCK and LE conforming assembler
Concerning the note, I have a requirement to be able to find the caller of a called program. The caller and called program are both COBOL running in batch. I found from the list that I should try CEETBCK. So I am trying to write an assembler routine to do this. Since I a novice at assembler I was wondering if anyone had a sample they would be willing to share showing me how to use CEETBCK Every time this question comes up and this happens every month or so (or something similar) I tell posters that you should submit an IBM REQUEST (via marketing and reference the existing SHARE requirement: SSLNGC0313587 - New LE Callable Service to get (various) Program Names A new LE callable service (with capabilities well beyond CEE3GRN) should be created to obtain various program names. This should include options to obtain: - The currently executing program's name - The name of the program that activated (Called, Invoked, whatever) the currently executing program - The name of the program at the top of the current LE enclave - The name of the program at the top of the current LE thread For each of these, sub-options may be required to provide information such as - Any alias by with the program was entered - Any long-name (with mixed characters) as supported by the Binder - Any Entry-point name when other than the modules name Finally, although not necessarily a part of this callable service, it would also be desirable to be able to obtain the data set name (HFS, PDS, PDSE, LPA member, or whatever) from which each of these entities was obtained. *** This SHARE requirement was submitted to IBM in 2003. The need for this functionality comes up repeatedly in IBM-MAIN (and similar forums), but until/unless IBM customers communicate to IBM thru official channels that this is IMPORTANT for IBM to provide a solution to, I don't think they will actually do so. Please, PLEASE, Even if/when you do find a work-around make certain that your business needs are communicated to IBM. -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html

Re: CEETBCK and LE conforming assembler
The order would be that the originating Cobol program would call another Cobol program. The called Cobol program wants to know who called it because it can be called from many different programs. The called Cobol program would then call my assembler program which would traverse back though the called chain using CEETBCK and report back who called it.

Now I need a way for Cobol Program B to find out it was called by Cobol program A. I was going to use CEETBCK to do this. Brad, Let me ask one more clarifying question. First some background just to establish a level-set to ensure we are discussing the same thing. COBOL will place the character string located in the PROGRM-ID into the object code. This will also be located in the load module along with the rest of the compiler generated stuff. When the object code is linked into a single load module, it is possible (using the NAME control card) to specify a name which is different from the name specified by the PROGRAM-ID. This occurs quite frequently when code is cloned to a different source module and and the PROGRM-ID field is not updated. Additionally, there is the case where the calling modules is part of a statically linked composite compose of several different object modules. The load module name may have no relationship top COBOL program you are interested in. Actually, there could be several object modules in a statically linked composite all of which dynamically call the subprogram. The question is which caller's name is needed. PROGRAM-ID, Load module or both? For my information, can you shed some light on what the name of the calling program will be used for?
