POLYLINE LAST or POLYLINE <ABSOLUTE|RELATIVE> ...three or more x y z point coordinates... ENDPOLYLINE In the first form of this command, the last polyline is replotted, which is most useful if it was defined as a relative polyline. In this way, pairs of MOVE and POLYLINE LAST commands can be used to plot several instances of the same polyline without having to reenter its coordinates. In the second form, the keywords ABSOLUTE and RELATIVE specify the polyline type, with ABSOLUTE assumed if neither keyword is specified. The following lines then specify the polyline coordinates (x,y,z), one point per line, with the list terminated by the ENDPOLYLINE command. Line segments are drawn from the current point to the first polyline point, then between successive points of the polyline up to the last one. This was an unfortunate choice in the CORE proposal, for it means that a polyline command does not define a constant graphical object, but instead must be prefixed by a move command to supply the starting current point. For a relative polyline, each coordinate point is relative to the new current point established by the preceding coordinate point. The polyline coordinates are saved internally in a buffer of fixed size (currently 256 entries); if more coordinates are entered, excess ones except the last are discarded, and a warning message is issued. The truncated polyline will still be plotted, however. The POLYLINE LAST command can later to issued to plot the same polyline again without having to reenter its coordinates. Any coordinate scale factors in effect at the time a relative polyline is plotted are temporarily applied to the coordinate values, but the original coordinates are restored after the polyline is actually plotted. This can be useful with the POLYLINE LAST command to obtain multiple instances of a polyline with varying scale.
