And we are now rid of all our zero initialization
problems. That only took a couple of months ...

Sorry, I've been here before. The decision is

No argument on the usefulness of a good traceback.

I "know nuthink!" (to quote Sgt Schultz) of current MS Visual C/C++ but
a search on web and the MS and MSDN didn't find me much useful about
what it actually does that's any different than any other compiler--I
couldn't even find a /trace switch in the commandline for the compiler.

Lynn,
the only reason for switching you mentioned is the traceback implementation.
Care to tell us what the other reasons are?

Tracebacks in the field are a given feature of
Visual C++. They are immensely helpful as I have
crashes at customers sites go to our website and
automatically tell us that the app is crashing and
where. When one has several thousand customers,
detailed crash reports are a necessity of life.

That, to me at least, seems a shame to not check it out once you get the
code base cleaned up. I really can't fathom what you can gain from
having auto-generated C code over Fortran for the computational
portions...but, of course, it's not my code.

Traceback information isn't a function of the language per se; it's a

Not even going to try. Bought a group license
of FOR_C and will be using that next.

Moving to C++ will give us another excellent
benefit, crash tracebacks from our users with
function names and code lines. Our user
interface does this and is wonderful. The code
tracebacks that we get from OW F77 are worthless

Well, the root of the problem there is badly written code to begin with
as opposed to the fundamental problem of having an insurmountable problem.

Granted, altho one could do a search on the API names instead of the
test and ensure at least seeing all the calls.

We are still working on getting rid of the zero
initialization of our OW F77 code. All the crashes
are gone, now we are working on computational
differences. Do not do this at home ! <g>

We are currently using OW F77s signed integers for
pointer storage and have not gotten burned yet. It
is just a little scary. We do have some old code
that is
if (iptr .gt. 0) then
do some work
end if
that has been changed to
if (iptr .ne. 0) then

But we continually find that we have missed a couple

I should note that while unsigned integer types have not been
introduced, the F2003 Standard did define an intrinsic module for C
interoperability and a set of intrinsic functions to handle the details
in a Standard-conforming way between compatible compilers.

While there's no absolute guarantee that two randomly chosen C and
