I have 3000 load modules with no source code. I would like to know what shall I do if any of them needs any modification?

Thanks,

It's work, but there are free dis-assemblers out there that work fairly well......

Hello Vijay and welcome to the forums,

Try here:

Keep in mind that source created from the executable is not very maintainable.

If there are some critical modules that may need modificaton n the near future, it would be a good thing to begin re-coding them.

Hello again,

Were these originally assembler or some other language?

Hi Dick,

Most of the load modules are from Cobol.

Are you able to understand "Assembler" code?

Vijay,
Please share the technique you used to convert from COBOL load modules to Assembler or COBOL source.

Hello,

If 3000 load modules were involved and the work ws completed that quickly (just over a day), my guess is that a copy of the source was located. . .
