If one uses
EXTERNAL foo ! or PROCEDURE() :: foo
foo might be either function or a subroutine. However, using
REAL :: foo
EXTERNAL foo ! or: PROCEDURE(REAL) :: foo
foo is a function. However, gfortran happily allows the following:
EXTERNAL foo
REAL foo
CALL foo() ! <- wrong
NAG f95 diagnoses:
FOO has been declared as a function, not a subroutine
ifort:
The CALL statement is invoking a function subprogram as a subroutine.
g95:
Error: SUBROUTINE 'foo' at (1) cannot have REAL type
