I'm not totally sure it's fair to bring up a version of a language that is twenty four years earlier than the one under discussion. (and for a thought to make some people feel old, 1966 is closer to 1990 than 1990 is to today).

I am. The point is to show Fortran 90 evolved a lot, which is indeed, a good thing. Remember, F66 was influenced by Speedcoding which was, in turn, influenced by assembly, because practical, high-level languages were still in the learning phase. In other words, early Fortran (e.g., FORTRAN for the IBM 704 on punchcards, which my mom coded in at NUQ) was just barely higher level than assembly, but later versions improved to gain additional features which made coding in it less onerous and more productive.

Age is an irrelevant, consumerism fallacy; the contextual history including the players involved, machines available, problems to solve and lessons learned, is far more important.
