FORTRAN

Early and highly influential programming language designed by IBM in the 1950's, by now primarily used in numerical and scientific computing but on top of the usual inertia and the wide availability of libraries, FORTRAN can produce numerical code that is significantly faster that what you can expect from languages like C and Pascal. While Fortran was a major influence on the European Algol languages in the late 1950's, things have essentially turned around 180 degrees with all FORTRAN standards since the early 70's being heavily influenced by structured Algol derivatives like Pascal and Modula-2.

Classic FORTRAN is always spelled all caps, Fortran 95 and later however are expected to be formatted as other nouns. We tend to use the older conventions here since only a couple of F95 OS/2 implementations showed up and they did not sell well so the bulk of OS/2 programming has traditionally been done in classic FORTRAN.
