WG - Fill wedge
WG r,q1,qc(,qd)[;]
r ; Radius in user units or graphics units		q1 ; Start point angle
qc ; Arc angle	qd ; Chord angle

•Fill in a wedge centred on the current position with radius r, start point angle q1, arc angle qc and chord angle qd.

•After plotting, the cursor returns to its point of origin.

•Plotting is performed whether the pen is up or down.

•When scaling has been performed, the circle is plotted in user units.

•Also, when scaling has been performed, the value for r is a real number.

•When there is no scaling, the circle is plotted in graphics units.

•When there is no scaling, the coordinate value for r is an integer number.

•The value for q1 is a clamped real number.

•When q1 is positive, the positive direction of the X axis relative to the current position is set at 0 degrees and the start point is sought in the counterclockwise direction. The opposite occurs when q1 is negative: the negative X axis is set at 0 degrees and the start point is sought by going clockwise.

•The value for qc is a clamped real number.

•Plotting proceeds counterclockwise when qc is positive and clockwise when it is negative.

•The value for qd is a clamped real number.

•When qd is not specified, the chord angle is the default value ( 5 degrees ).
