            When using /NEW given radii may be fractions.
        IX0=ix, IY0=iy Center of circle (device coord). in, out.
            Input IX0, IY0 ignored when /NEW used.
        /DOTTED show a dotted circle, else solid.
        THICK=thk Circle thickness (def=1).
        /MAG or MAG=mag Use a magnified cursor (def=5).


      rad = array of circle radii (pixels). in, out
