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.

PLANT information :
* Data input groups used:  4
