Abstract
A register control instruction is added in a stored program computer and uses the same OP code as used for an existing storage instruction. A non used bit state in the existing storage instruction identifies the instruction as a register control instruction rather than a storage instruction and causes logic to generate a control signal for inhibiting the storage operation whereby the storage address is used for addressing a register instead of storage and data is transferred to or from the addressed register as per other control information in the instruction. The bit state identifying the instruction as a register control instruction is converted to a used bit state of the storage instruction so as to invoke an address update operation normally invokable by the storage instruction to update the storage address used instead for register addressing.
