Wow! Thanks, Joe! You always answer so quickly, you must have a small parish to have this much time for the calculators!

However, unlike ATAN2, ARG will not always work

Code:
  ATAN2_UNUSEDYX(YY,XX)   BEGIN //MY ATAN2   IF XX==0 AND YY==0 THEN    RETURN 0; //CONVENIENT;   END;   //-π..π    RETURN ARG(XX+*YY);//BUILT-IN HANDLES MOST // the heiroglyphic is imaginary i  END;
