are dependent on the first axis in the plane (linear axis).
-- I and J in the Xp--Yp plane whenever the linear axis is the X axis
or, alternatively, an axis parallel to the X axis.
-- J and K in the Yp--Zp plane whenever the linear axis is the Y axis
or, alternatively, an axis parallel to the Y axis.
-- K and I in the Zp--Xp plane whenever the linear axis is the Z axis
or, alternatively, an axis parallel to the Z axis.
Address R can also be used to specify the radius of an arc.
