(IT) An early
compiler for
mathematics developed by A.J.
Perlis et al at Carnegie Tech
ca 1957. IT was originally written for the Burroughs 205,
then the
IBM 650.
IT was the forerunner of RUNCIBLE, GATE, CORRELATE and GAT.
IT source code was converted to PIT, thence to SPIT.
IT-2 produced machine language directly, IT-3 developed at
Carnegie added double-precision
floating-point.
