All I can suggest is the following:
- Run an AMBLIST to find out how many CSECT names there are in each of
your LMODS.
- Disassemble each CSECT in turn and then try to figure out what Fortran
source code generated it.
I did come up against a similar problem more than 20 years ago, caused

Any idea how to reverse engineering the load modules?
