Affects: HPGL output to file or plotter
This parameter determines which plotter pen will be used to draw the point, lines, symbols, etc. which represent the data points of the graph. It, and the related "Axes pen" and "Marker pen" parameters are all initially set to the same number (1) to allow for quick single-colour plots.
Selecting pen number 0 suppresses plotting of those items.
