Re: Disassembler

Keith,
Just in case it got lost in the thread, to the best of my knowledge the
Source-Recovery products/services/whatever are limited to IBM mainframe COBOL.
If you are working in another environment / with another compiler, I am not
certain (actually I doubt) they can help you. If you ARE in an IBM mainframe
environment, I have heard VERY GOOD reports on what they can do.

Reading in comp.lang.asm370 I came across the following item which may
be of some interest:

It's a patent issued in 1999 by the USPTO for a disassembler, which
wasn't a
new concept back then (I've written my first disassembler in 1982).

The problem is that the language of patents is so arcane that it's
difficult
to spot the original elements of this patent, or if there's any
originality
in it at all. Hopefully, one of you will dig something up.


It appears to be more than just a dissassembler, based on the generated

assembly code it looks for known patterns charateristic of the IBM
Cobol
compiler and attempts to symthesize the Cobol source, as nearly as I
can
tell in 5 minutes. But this has been done for many years, I am not
sure
what is novel here.

Perhaps there will soon be an answer to the perennial "Where can I find
a cobol disassembler?"


Apologies if this is an obvious question.... but where can I find a cobol
disassembler ? I've read the instructions and I am none the wiser !!!

[Feel free to tell him where you got the reference.]
Note: I have no direct involvement or interest in them. I have just worked
with Jim off and on for the last ten years.
