Ok, thanks! Those items have unique long type id number. Maybe I'm wrong but to me string keys sounds slow. Perhaps binary mode is quicker ( http://gambasdoc.org/help/comp/gb/collection/_new?show ). But I think this is the right way to go!
I didn't find this from documentation, so do anyone know what $ sign means at declaration.
