Hi,

IS there any Rexx code available to convert cobol load module to cobol program or source code, I remember i saw some Rexx code in this forum previously, but now i could not find it now.

Regards,
Magesh

The only load modules that can be, with a very high degree of confidence, converted to source are BMS maps, but doing so in REXX is (virtually) impossible, as REXX does not have any way of accessing U-type records...

Converting any high-level language to source is simply not possible, although Hex-Rays' IDA Pro with the Hex-Rays Decompiler does do a pretty good job when processing C.

I'm sure that if you give them a couple of million dollar, they would be happy to produce something that can do the same for z/OS load modules that are the result of compiling Cobol.

I remember seeing a poorly-titled one somewhere, but it was about (or ended up being about) getting the compile information from a loadmodule.

Turning an "object" into Cobol source is a highly complex thing. You either pay a company to do it (google will find them) or you "disassemble" the Cobol program and treat it as an (oddly-written) Assembler program.

Or you hope you have a source close enough, that just an inspection of the object code will get you there.

So, more detail of the specifics of what you want.

The source code is one of most important assets your company may have. There should be several generations of backups, including backups kept offsite.

I realize my comment may not be of much help to Mangesh, but may help others.
