Description
  
This routine defines the new coordinate system.
  
Prompts for and stores M, the new origin's x–coordinate.
  
Prompts for and stores N, the new origin's y–coordinate.
  
Prompts for and stores T, the angle
θ
.
  
Loops for review of inputs.
Checksum and length: 1EDA 15

  
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.
 

 
Swaps positions of coordinates back.
  
Halts program to display U.
  
Halts program to display V.
  
Goes back for another calculation.
Checksum and length: 921A 69
  
This routine converts from the new system to the old
system.
