| WE have a program a programmer wrote for us. He is long gone.
We hired another one but it appears the source for the file is misisng or he
took it with him. I understand there are decompilers out there for this sort
of thing. Is there a free or cheap one I could use.
The environment is RISC6000 running AIX 5.1

perhaps they will work. It is standard MicroFocus COBOL.

What compiler? Brand name is good enough.
Was it compiled with the debugger option on?
A decompiler cannot recover information that doesn't exist in machine
code. Without debugging information, you'll get a program that
compiles but has meaningless names.

| No - it doesn't work for Micro Focus COBOL. Although with Micro Focus, if you
have an .idy file, then you *may* be able to get source out of that.

For a company that does exactly what Robert says can't be done (but as far as I
know is limited to IBM mainframe COBOL missing source code), see:

A glance at their marketing demo confirms everything I said.

You're out of luck. The debug file (.idy) doesn't contain source
names.

Robert,
My company used this technology for recovering a couple of lost programs
at Y2K time. If you send them record descriptions that use the names
you want to have in the program, they will "fit" the generated names to
the "desired" names. While this does not fix everything, it can
certainly help.
You are left with procedure-names and some items like level-66,
level-77, and level-88 to fix yourself, but it will give you a leg up on
the job of understanding a program with lost source code.
All of that said, while we had a number of executable programs for which
we could not easily find the source, we did find over 90% after more
exhaustive searches. (In most cases, the programs did not follow our
rules of having the source program and executable use the same name, or
the source never got transferred from old libraries to the newest ones.
I would try hard to track down that original programmer. It is almost
certain that she / he left the source code behind, and maybe the
original poster simply doesn't know where to look. If the programmer
didn't leave the code behind (a bad practice for both him and the
company), she / he may well have a copy.
