- There are also several revisions to the ieee-488 'standard', and either
- the analyzer or the plotter may not support an 'equal' standard. HPGL
- also had several revisions, the earlier did not include CIrcle and
- ARc commands; latter versions did. Many CAD packages still don't
- output arcs and circles, rather they output several line segments
- to plot the chords around the arc or circle. Also, the X and Y points
- the analyzer outputs may not be within the plotter's limits.
