It's in that direction yes, but the distinction that you mention, which is 
essentially the same as Pascal 'function' versus 'procedure', or Visual Basic 
'function' versus 'sub', is just a distinction of two variants of subroutines.

Up above there is the more general concept of a routine, where there are more 
possibilites than just subroutines; Python generators are one example.

As I mentioned earlier, in Eiffel, which is a more modern language than Fortran, 
routines are still called routines. And specialized terms include "routine". So 
it's not like that language independent terminology has been phased out in 
general; it's mostly only in the C syntax family (e.g. Python operators come 
mostly from C) that "function" is, misleadingly and with associated severe 
constraints, used as a general term.
