FORTRANSIT
     
         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 card}s
        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).
