METHOD FOR SUPPORTING ADDRESS INTERACTION BETWEEN A FIRST ENTITY AND A SECOND ENTITY, CONVERTER FOR ADDRESS INTERACTION, AND COMPUTER SYSTEM

To support address interaction between a first entity and a second entity which use different addressing modes with address types in different specification languages and with address values of different semantics, an address type with an address value according to the first addressing mode is converted to a correspondent type of the other specification language. The correspondent type is so constructed that it contains both the address value according to the addressing mode of the first entity and the address value according to the addressing mode of the second entity.
