Purpose: Plots to the X,Y coordinates in the order listed using the
current pen up/ down status. PA; sets absolute plotting.
Parameters: Pairs of integers representing plotter units if scaling not
in effect, otherwise user units, integers or decimals.

Purpose: Plots, in order, to the points indicated by the X,Y incre­
ments, relative to the previous pen position. PR; sets rela­
tive plotting for PU or PD with parameters.
Parameters: Pairs of integers representing plotter units if scaling is
not in effect, otherwise user units, integers or decimals.
