If scaling point P1 is assigned negative (-) coordinates and
P2 is assigned positive coordinates, origin is automatically
set at center of plot area.

This scale corresponds to e centimeter unit of the platen area with the origin (0,0) at
the current location of P1. Since the scale corresponds to a unit measure (centlmeters),
the P2 scaling point is not referenced.

statement without parameters is input. Origin is set at P1
and platen is divided into units 1 cm in length.
Coordinates of P1 and P2 in internal units of plotter are:
P1 (520, 380) and P2 (15720, 10380)

P1 and P2 remain unchanged.
