Program Instructions:
1. Key in the program routines; press

when done.
2. Press
W
D to start the prompt sequence which defines the coordinate
transformation.
3. Key in the x–coordinate of the origin of the new system M and press
f
.
4. Key in the y–coordinate of the origin of the new system N and press
f
5. Key in the rotation angle T and press
f
.
6. To translate from the old system to the new system, continue with step 7. To
translate from the new system to the old system, skip to step 12.
7. Press
W
N to start the old–to–new transformation routine.
8. Key in X and press
f
.
9. Key in Y, press
f
, and see the x–coordinate, U, in the new system.
10. Press
f
and see the y–coordinate, V, in the new system.
11. For another old–to–new transformation, press
f
and go to step 8. For a
new–to–old transformation, continue with step 12.
12. Press
W
O to start the new–to–old transformation routine.
