HP 5961-0509 manual Last unmatched coordinate, PA, Plot Absolute

•When you use the Symbol Mode (SM) command, PU draws the specified symbol at each X,Y coordinate. When you use the polygon mode (PM) command, the X,Y coordinates enter the polygon buffer (for use when the polygon is edged or filled).

•Coordinates are interpreted in current units: as user-units when scaling is on; as plotter units when scaling is off.

•Whether the PU command uses absolute coordinates or relative coordinates (increments) depends on the most recently executed PA or PR command. If you have not issued a PA or PR command, absolute plotting (PA) is used.

Note	If an odd number of coordinates is specified (in other words, an X
	coordinate without a corresponding Y coordinate), the printer ignores
	the last unmatched coordinate.
