- fortransit — (language) Fortran Internal Translator. A subset of Fortran translated into IT on the IBM 650. It was in use in the late 1950s and early 1960s. Compilation took place in several steps (using punched cards as the only input/output media). FORTRANSIT was converted to IT Internal Translator which was converted into SOAP and thence to machine code. In the SOAP -> machine code step, the user had to include card decks for all the subroutines used in his FORTRANSIT program (including e.g. square root, sine, and even basic floating point routines).
