Fortran is not C and makes a real distinction between functions and 
subroutines. It is not possible to call a function without 
assigning/using the return value somehow. Additionally, 4.5.5. 
explicitly states:

"The FINAL keyword specifies a list of final subroutines."

Note the word "subroutines" -- and not "procedures" which denotes both 
subroutines and functions.
