Description
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).
Calculates cost (T) and –sin(T) in X– and Y–registers.
Calculates (X – M) cos (T) + (Y–N) sin (T) and (Y – N)
cos (T) – (X – M) sin(T).
Stores x–coordinate in variable U.
Swaps positions of the coordinates.
Stores y–coordinate in variable V.
Swaps positions of coordinates back.
Halts program to display U.
Halts program to display V.
Goes back for another calculation.
This routine converts from the new system to the old
system.
Prompts for and stores U.
Prompts for and stores V.
Pushes V up and recalls U.
Pushes U and V up and recalls T.
Sets radius to 1 for the computation of sin(T) and
cos(T).
Calculates cos(T) and sin(T).
Calculates U cos(T) V sin(T) and U sin(T) + V cos(T).
Pushes up previous results and recalls N.
Pushes up results and recalls M.
Completes calculation by adding M and N to
previous results.
