Ahh, FORTRAN. I have fun, memories of FORTRAN. Write out of college in the mid to late 90's I worked with the language quite a bit. I was working for a logistics company and we spent a lot of time calculating routes, costs (fuel, maintenance, etc.) and the like using FORTRAN. The move from F77 -> F90 -> F95 was rather pleasant.

When the web started to become popular and Microsoft started including IE on desktops, I ended up writing CGI scripts, in FORTRAN!, to model reports in HTML. We were moving from OpenVMS to Sun Solaris boxes, which allowed use to move way from writing text based reports that people viewed on a terminal to HTML pages that would easily allow CSV files to be downloaded. I was a mess for few months. I don't think I have ever fully recovered.

Yep, my first bit of web based programming was FORTRAN 95 and DCL. I had to cobble a cgi library together where I put in something that acted like, but wasn't exactly, authentication and security.

By the mid-2000s the system had been migrated to some monstrous application that was mostly Java, but there were still FORTRAN bits handling the math and numerical back end, but I had moved on by then.

I still have nightmares about the system, but writing the FORTRAN code was also easy. Using it in the right spot was always the hard part.
