Dear Wayne,
How are you doing?
Don't you rather want to call this new macro method: Roi.getStackPosition(i)
or something similar which would make it a little bit more self explaining?
I guess this the macro method corresponding to the ij.gui.Roi.java getPosition() method, or am I wrong?
Have a nice week-end.
Kindest regards,
Philippe

The latest ImageJ daily build (1.52r48) adds the Roi.getPointPosition(index) macro function, which returns the stack position of the point with the specified index. Here is an example:

   for (i=0; i<Roi.size; i++)
      print(i+" "+Roi.getPointPosition(i));
