FORTRAN
From Computer History Wiki
Fortran, better known as a "FORmula TRANslator". Its primary use was in Scientific and Engineering disciplines. FORTRAN runs on big machines like mainframes, supercomputers, minicomputers and even down to 8 bit CP/M machines. It's a relatively portable language, however many vendors have extended the language in unique and incompatible ways. However over the years FORTRANs popularity has significantly waned, although there is still a significant amount of legacy code out there.
