That was FORTRAN-77. ANSI dropped the Roman numeral business because
vendors were appropriating Roman numerals for their own "enhanced"
versions of FORTRAN IV. Consider, for example, Univac 1107 FORTRAN V
(late 1960's).
The other issue is that the Roman numerals didn't identify a specific
dialect of FORTRAN, just a basic ill-defined subset. So, instead of
punching a "D" in column 1 of a card to signify double-precision in
FORTRAN II on the IBM 7090, there was a DOUBLE PRECISION (or DO UBLEP
RECISION) type statement in FORTRAN IV.
