.REFINED ROTATION ANGLE, X & Y SHIFTS: [angr],[xsr],[ysr]
[The rotation angle, the x-shift value, and the y-shift value from the refinement cycle. These three values can also have been unsaved in the above manner from another document file, or if the 'SA' is performed in the same session (procedure run) as the second cycle, they may simply be current register contents (see below).
The three registers specified on the operation line are output registers, and receive the vector sums for the rotation and shifts.
