My dad is an engineer with 30 years experience in Tenaris. He has old papers that are coded in different lenguages and he needs this software, FORTRAN, in version FORTRAN 77 if possible. Does anybody know where can I find a free version or a free version variant of it? Since he needs to check over 50 documents from the 90s and theres no single software that compilates such lenguage, because its in the main FORTRAN lenguage.
-Thank you, Mobi.
