Hi R'Shmuel AMV"SH,
I used Dick Thornton's Disassembler on File 234. It seemed to work.
I did not open an IBM ticket.

Thank you for the suggestions.

Regards,
David

It sounds as if the disassembler is not generating an EXTRN TSAUXWRK from the 
ESD entry. Which disassembler are you using?

Subject: Disassembly/Reassembly

Hi,
I have been given a Load Module and source code.
The Source Code, however, does not 100% match the Disassembled Load Module.
This module has been running in production since 1994.

With that preface ...
I tried reassembling the disassembled module source and have a problem.
One instruction says:
L     R2,=A(TSAUXWRK)
Later in the program, I see the following in the disassembled source
         DC A(TSAUXWRK)
Yet, the definition of TSAUXWRK appears nowhere in the disassembled
source, causing a ASM044E.
I looked in the source provided and it has:
TSAUXWRK CSECT
in the middle of the program. (When I assemble this, even though it is
not the correct source, I get a clean assembly.)

Has anyone encountered anything like this (addressing a CSECT as an
A=CON works, but, only with original source)?
Is there a remedy for this?

Thanks and regards,
David
