Even if 'i' and 'I' are in different scoping unit, there is nothing unitialized
:
('i' is the external 'I', and 'ii' the internal one)

       integer j(5)
       I=5
       j = 42
       do ii = 1, I
          j(ii) = ii
       end do
       print '(A,I0,A,5(I0,1X))', 'I = ', I, ' j = ', j
       end
