Dummy Array Arguments

There are two main types of dummy array argument:

• explicit-shape -- all bounds specified;

    REAL, DIMENSION(8,8), INTENT(IN) :: expl_shape

  The actual argument that becomes associated with an explicit-shape dummy must conform in size and shape.

• assumed-shape -- no bounds specified, all inherited from the actual argument;

    REAL, DIMENSION(:,:), INTENT(IN) :: ass_shape

  An explicit interface must be provided.
• dummy arguments cannot be (unallocated) ALLOCATABLE arrays.
