ABSTRACT OF THE DISCLOSURE A plurality of peripheral devices having physical addresses are accessed by a host processor by use of logical addresses which are utilized by the various programs in a multiprocessing enviroment. Input/output tables are arranged to include pointers for relating the logical address provided by a programmer to the physical address of the device thereby providing necessary device specific information to the peripheral controller coupled with the peripheral devices. The input/ output tables are structured so that pointers relating the physical and logical addresses may be changed to reassign the logically addressed device to another device and accordingly to point to another physical address. 1.
