I haven't had my coffee yet, and I only just now realized that you state that
everything is read from a data file, and written to a data file. In that case,
I completely agree with David--all you want is SPAWN. Use IDL to write out the
input file, spawn the command to run the compiled Fortran program, and then
read the output file back into IDL. That's the simplest and most direct
approach. Anything else would be a waste of time.
