HP 5961-0509 manual PM2, Example Using the PM Command

(PM2)

Use (PM2) to close the current polygon (or subpolygon) and exit polygon mode. Remember, if you have not closed your polygon, executing (PM2) adds a point to close the polygon. Refer to “Pen Status and Location” in Chapter 17, Introduction to HP-GL/2 Graphics.

The following example draws the surface area of a 3-prong electrical receptacle as a series of subpolygons, then fills and edges it using the FP and EP commands, respectively.
