! 6.3  Argument association
! An assumed-rank dummy argument may correspond to an actual argument of
! any rank. If the actual argument has rank zero, the dummy argument has
! rank zero; the shape is a zero-sized array and the LBOUND and UBOUND
! intrinsic functions, with no DIM argument, return zero-sized
! arrays.  [...]
