The ID property returns the permanent ID number of any button, field, card, background, window, or menu in the current stack. The ID of HyperCard is WILD. The ID of a standalone application is its creator code. All objects except stacks have IDs. You can’t change the ID number of an object, window, or menu. If an object doesn’t have a name, HyperCard returns the ID instead. The adjectives abbreviated, long, and short return various forms of a card’s ID. (Click Demo Script.)
