CHAPTER 4 HP-GL/2 - 27
 r specifies the radius of the circle. A positive value for r places the 0º reference point onto the positive x-
axis and a negative value for r places the 0º reference point onto the negative x-axis.
 The value for q1 is a clamped real number.

 q1 specifies the wedge starting point relative to the 0 degree reference point.
 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.
 qc specifies the angle of the wedge in degrees.
 The value for qc is a clamped real number.
 Plotting proceeds counterclockwise when qc is positive and clockwise when negative.
 The value for qd must be an integer from -32,768 to +32,767.
 When qd is not specified, the chord angle is the default value ( 5 degrees )

RA - Fill rectangle absolute
RA X, Y[;]
X ; X coordinate of opposite corner for the rectangle
Y ; Y coordinate of opposite corner for the rectangle
 X and Y coordinates are absolute coordinates in current units.
 Fill the rectangle formed by the current position and the opposite corner specified by X and Y.
 After plotting, the cursor returns to its point of origin.
 Plotting is performed whether the pen is up or down.
