S0C7 abend offset does not match my listing

Batch step abended S0C7. I have the offset from SYSOUT (reason 00000007). Pulled the compile listing from SDSF and I cannot map the offset to a statement. Compiled through Endeavour with our standard options.

Job itself has run for years. Pretty sure the bug is in the program not JCL. Do I need OFFSET or LIST to track this down?

Recompile with OFFSET,NOLIST. The condensed procedure division map lines up offsets to verbs. Make sure listing timestamp matches the load module or you will chase ghosts.

Recompiled with OFFSET. Offset pointed at an ADD on a COMP-3 field. Input had low values in a trailer count from a vendor layout change. Fixed the copybook.

Saving this. I always stare at the dump and get nowhere.
