    - parameter of fun1 is not a reference parameter
      pt1 is therefore unchanged
      10 20

    - parameter of fun2 IS a ref. param.
      pt2 is modified
      14 40

    - parameter of funB is not a ref. param.
      pt3 is unchanged
      50 60

    - parameter of funD is a ref. param.
      also parameter of funC is a ref. param.
      both funD and funD can modify pt4
