The informationin this section enables you to achieve the following results
in your programs:
●Use absoluteand relative coordinates when plotting.
●Draw 1ines,arcs, and circles.

ac
AAxc, JC, angle [,chord angle ;]
wherexc indicates thex-coordinate ofcenter of arc, ycis they-coordinate of
center of arc. angle is the angular size of arc, from –360 to +360, and the
chord angle isthe angle subtended by chord, from ().5 to 180.
Thiscommand draws an arc using absolutecoordinates fromthe currentpen
position,as specified. Afterdrawing the arc,the currentpen position is atthe
end of the arc.
rc
AR d.w,d?’c,an<qle[,chord atl<yle;]
whered.m indicates the x-coordinate of center of arc relative to the current
location, dvc is the y-coordinate of center of arc relative to the current
location,angle is the angular size of arc, from –360 to +360, and the chord
angle isthe angle subtended by chord. from 0.5 to 180.
Thiscommand draws an arc using relative coordinates from the current pen
position,as specified. Afterdrawing the arc,the currentpen position is atthe
end of thearc.
