A complex relocatable expression can only specify an A- or Y-type address constant. These expressions contain two or more unpaired relocatable terms, or two or more negative relocatable terms in addition to any absolute or paired relocatable terms. A complex relocatable expression might consist of external symbols and designate an address in an independent assembly that is to be linked and loaded with the assembly containing the address constant.
