There may be another way. For example, in investigating polygons, I found a
polygon structure. In that structure was all the x and y data as well as
the number of points within the polygon (and some other stuff). As such, I
was able to open polygons and redo their shape, add to the number of x,y
and without using the toolbox OPENPOLY function. One might be able to do
the same for regions.
