Selection Lists Example (VBA)

If you specify a positive, non-0 mark for an object (e.g., 1 or 2 or 3, etc.) and then specify to select only the objects with that mark, then the resulting selection list contains only those objects with that mark. This selection list is independent of a selection list created by selecting all of the objects.
