Short for Formula Translation, Fortran was one of the first programming languages. Development of FORTRAN began in 1954 by John Backus and members of the IBM team, and was first introduced to the public on October 15, 1956. It was a very popular programming language and is still used today.

Should I use "Fortran" or "FORTRAN" in my writing?

According to the Microsoft Manual of Style you should not use all uppercase "FORTRAN" and it should never be spelled out as "Formula Translation." If you're writing about versions of FORTRAN before Fortran 90, use FORTRAN in your writing. However, if you're writing about Fortran in general or writing about more recent versions of Fortran do not uppercase the word.
