Re: double confusion

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 ?

But these declaration are located onlz _once_ at the begining of the
file (before the main routine starts). Fortran requires its
declarations "within the main routine" and within every
subroutine/function where i'm going to use the this function, and what
confuses me somewhat more, that it's just required for double
precision, but not for integer or real ...
