TNX, it's working, but (It seems to be quite a while since I wrote
frotran77 the last time) this is not similar to moth other languages.

Why do I have to declare r wihin the calling program? I've already
declared r as double precision in the function definition. It's more
clear to me to declare c and a,b but r ... ?

What logic is behind that? It's unlike other languages, isn't is?


How is it different from C ?

If the subprogram and the main program were in different files and compiled
separately how could you ensure that the main program knows what return
type the function has ?
