There are commercial products that will de-compile a load module. I've seen it used, though some time ago.
The COBOL code it generated was not very friendly. All of the datanames, paragraph names are arbitrarily assigned. The code did not compile, there were areas that the de-compiler could not determine what the program was doing. It took MUCH longer to reconstruct a useable piece of code than it would have to code it from the start. The only reason we chose to go with the de-compiler was there was some of the logic in the program that we just didn?t know.
I don?t even know where to start looking for something like that now. I might try contacting IBM. They probably get asked this and may have a resource for you.
