A control store having a first portion for storing system operation instructions (opcodes), a second portion for storing control store addressing information, wherein the second portion includes a greater number of storage locations than does the first portion in order to efficiently store different control store address information which may be required for the same opcode. Addressing apparatus coupled to address a location in the first portion and any one of at least two corresponding locations in the second portion is provided, thereby minimizing the number of locations required in the first portion of the control store.
