Fortran was the first programming language. Fortran began in the 1950s and has had a number of transformations. The application area of Fortran is in science and engineering. Fortran 77 harks back to 1977, but the latest standard is Fortran 95. However, the 1970s and 1980s was perhaps the heyday of Fortran; the time when it was most popular. Generally, Fortran has been superceded as the main programming language within the science and engineering community by Matlab/Freemat. However, there still exists a vast amount of legacy code in Fortran and hence we still need a means of familiariaing ourselves with Fortran, even if we resist programming in the language. This webpage contains links to a number of tutorials that together give a quick and simple introduction to the essentials of Fortran 77.
