My Fortran exeriences date back 10 years or so, but these days there
was a Fortran preprocessor for the RS6000, an incredible thing. Together
with XLF there were giant speedups. For pure number crunching a fine
thing.
But, to all our luck, life is more than number crunching, and the last
compiler
I used before that machine died was Powerada from OCSystems ;-)
