Thanks for the info. I went from FORTRAN to FORTRAN II to FORTRAN IV to FORTRAN 66, then FORTRAN 77 with a brief dabbling in WATFOR. md On Thu, Apr 21, 2022 at 8:08 PM Michael Voorhis <mvoorhis@mcvau.net> wrote:
Wikipedia's "Fortran" page has descriptions for both Fortran-5 (Data General) and Fortran-V (Control Data).
from https://en.wikipedia.org/wiki/Fortran :
Fortran 5 was marketed by Data General Corp in the late 1970s and early 1980s, for the Nova, Eclipse, and MV line of computers. It had an optimizing compiler that was quite good for minicomputers of its time. The language most closely resembles FORTRAN 66.
FORTRAN V was distributed by Control Data Corporation in 1968 for the CDC 6600 series. The language was based upon FORTRAN IV.[64]
