Brief History
Fortran is 50 years old in 2007.
Created by IBM team lead by John Backus.
1957: FORTRAN I
1958: FORTRAN II (added linker)
1958: FORTRAN III (never publicly released)
1961: FORTRAN IV (clean up of II)
1966: FORTRAN 66 (first standard)
1977: FORTRAN 77 (many new things added)
1992: Fortran 90 (superset of 77, many additions)
1998: Fortran 95 (deleted a few 77 features; minor tweaks)
2004: Fortran 2003 (object-oriented, c-interop, and i/o)
200?: Fortran 2008 (co-arrays; minor tweaks)
Fortran 90 Additions
