"! %
Prompts for and stores X , the old x –coordinate.
"! &
Prompts for and stores Y , the old y –coordinate.
%
Pushes Y up and recalls X to the X –register.
Pushes X and Y up and recalls N to the X –register.
Pushes N, X , and Y up and recalls M .
%.
Calculates ( X – M ) and ( Y – N ).
!
Pushes ( X – M ) and ( Y – N ) up and recalls T.
-+.
Charges the sign of T because sin(– T ) equals –sin( T ).
Sets radius to 1 for computation of cos( T ) and –sin( T ).
θ
8T
´
¸8º
Calculates cost ( T ) and –sin( T ) in X – and Y –registers.
%º
Calculates ( X – M ) cos ( T) + (Y–N) sin ( T ) and ( Y – N )
cos ( T ) – ( X – M ) sin( T ).
