--- Comment #6 from MarkEggleston <mark.eggleston at codethink dot com> ---
Where a module is used:
module foo
implicit none
interface
subroutine dusty(n)
integer :: n
end subroutine
end interface
contains
subroutine bar(n)
integer, intent(in) :: n
real :: x
print *,"bar before dusty", n
call dusty(n)
print *,"bar after dusty", n
end subroutine bar
end module foo
subroutine dusty(n)
integer :: n
n = n - 1
end
program main
use foo
implicit none
integer :: n
n = 5
call bar(n)
end program main
The call to dusty in bar would be with an implicit interface were it not for
the interface block. I get the same warnings as in comment 5.
I would like to also issue a warning for the interface block but don't I know
where I could insert an code to issue a warning anywhere near the interface
block. I know where the dummy variable is processed from a lexical point of
view but I don't know where the interface block is handled. Some indication of
where to look would be greatly appreciated.
