Dan, The link to your Source Forge page you posted does not work for me. I found TREK7 it at https://sourceforge.net/projects/trek7/ <https://sourceforge.net/projects/trek7/>.
I tried to find the sources you started with. I found a ZIP file called trk7fsrc.zip <https://sourceforge.net/projects/trek7/files/trek7/status/trk7fsrc.zip/download>. When I compiled the first file, TREKA.FOR, I can see typos and lines extending past column 72. This could not be the original source code that worked at one time. Was this scanned? Has this been altered from a known working version, other than the scanning errors? Like, the lines that extend past column 72? The code clearly expects column 72 to wrap to column 7 of a continuation line, which is how Fortran fixed-format source works. Ancient Fortran should not be that hard to convert, especially if you know the original platform. I saw LIB$ calls, which leads me to believe this was maybe VAX Fortran? I see the use of FORMAT specifiers without lengths, like F, not F7.2. It would be nice to know the precise meaning of that non-standard Fortran. But, very new Fortran sill also accept FORMAT specifiers without lengths now. And, there is non-advancing support for Fortran I/O now. Fortran INTRINSICS should be straightforward. The library calls will be harder. Want help? What platform do you want to run the code on?
