  DISPLAY
   In this example, PLANT is used for expanding and/or contracting
   the Y-extent of the grid.

   It is useful in parabolic calculations; but it may be used more
   generally.

   The PLANT statements headed by SCXS??  would perform a similar
   function for the X-direction domain width, XULAST, provided the
   pointer AZXU is set to GRND.
