I have started working with FORTRAN in 1973, I have used the Microsoft FORTRAN Compiler on the CP/M 80 Systems and nearly all FORTRAN Compilers on Workstations (MS/DOS, Windows, Linux, Solaris, HP-UX) and mainframe computers (TR440, CDC Cyber, Siemens, IBM, Amdahl, VAX, PDP etc.)
Currently I am CTO of SOFiSTiK, a software company for scientific technical software and we DO use FORTRAN! Go for the web page www.sofistik.com to contact me.
