Is there a Capytalk expression which would convert an XY co-ordinate to an equivalent Angle/Distance or Angle/Radius...

The radius or distance would be:

(!x squared + !y squared) sqrt

The angle is arctan(y/x).  To see an example of how you can use the ArcTan module to compute the angle, see the Prototype called: MultichannelPan XY coordinates
