I am looking for a smooth, clean, and well documented way to get FORTRAN up and running on my Mac, which is running OS 10.6. I've done a ton of FORTRAN, starting in 1962, on a dozen different systems, but did my last programming circa 1995 in MPW Language Systems FORTRAN on the Mac. I have a more recent ABSOFT compiler, but it doesn't run on my Intel Mac under my present OS. I think I don't need fancy developer tools, just a command-line interface and good documentation on file handling, compiler, linker, etc. I volunteer my time in physics and engineering as adjunct faculty at a couple of universities and would need to do it at minimal expense. Any guidance you can provide would be much appreciated.
