Re: Online F77 information...

Which means that you're missing the point. Everything (well almost) that
you'll need to "understand" the F77 code is relevant to the F90 and later.
That's one of the nice things about this language, you can combine new F90
code with old legacy code in a piece-wise fashion. If you "learn" F90 from
the get-go, you'll be able to translate things into newer constructs.
Benefits all around.

There do tend to be older constructs with common blocks and self-memory
management that you won't see in today's code that might strike a newer
Fortran programmer as strange, but I wouldn't really characterize that a
reason to keep all of your code in F77.

Really in this day and age, no one should be writing new 'F77' code without
horrendous external requirements. The current language definition is F2003
and the nifty thing is that if you really must, you can choose to code
strictly F77 and add (even incrementally) newer language features as you
feel comfortable with them.

I just don't see any reason to limit yourself to F77 language features.

You make a good point, I'll have to find myself a good Fortran compiler
so that I can use the new constructs as well... I'll ask for advice
about compilers, but that's a discussion for a new thread.
