!No problem.  It just gave me an opportunity to get on my hobby
!horse about initialization expressions.  Regarding my hobby
!horse about specification expressions, try using CVF to compile:
!
module helper
   implicit none
   contains
      function dud(x)
         integer, intent(in) :: x
         character(selected_int_kind(x)+2) dud

         dud = repeat('x',len(dud))
      end function dud
end module helper

program sik
   use helper
   implicit none
   integer i
   integer, parameter :: s(-5:5) = (/(selected_int_kind(i),i=-5,5)/)

   do i = -5, 5
      write(*,'(4i4)') i,selected_int_kind(i),s(i),len(dud(i))-2
   end do
end program sik

!and compare with lf95 or g95.
