                | CALL  IGARC (XC,YC,R1,R2,PHIMIN,PHIMAX) |
                +----------------------------------------+
Action: This routine draws one or two arcs of a circle. If the two radii are not equal the area between the two arcs is filled according to the fill area interior style index and the fill area style index. The border is never drawn unless the interior style is hollow or the routine IGSET has been called with BORD and VAL = 1. If the arc's radii are equal only one arc is drawn. Parameter Description:
XC
X coordinate of the arc's center in world coordinate space.
YC
Y coordinate of the arc's center in world coordinate space.
R1
Radius of first arc.
R2
Radius of second arc.
PHIMIN
Starting angle (degrees.)
PHIMAX
Final angle (degrees.)
