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).
