Hexing the module you should be able to observe the date and time of the linking and compiling. You can see the pre-defined data in working storage and you should be able to see the literal pool. If there is anything recently changed, you might get a hint from that. If the latest changes were small procedure mods then your stuck with a byte by byte compare.

Sorry, other than writing a program that faithfully interprets the source code into what the compiler would create and having that program compare its results to the load module, no.
