SYNTAX      DIRECT   [<LABEL>] OR <dma>
            INDIRECT [<LABEL>] OR {ind}[,<next ARP>]

OPERANDS    0 . dma . 127; 0 . next ARP . 7.

EXECUTION   (PC) + 1 . PC
            (ACC(15-0)).OR.dma . ACC
            (ACC(31-16)) . ACC(31-16)
            Not affected by SXM.

DESCRIPTION The low-order bits of the accumulator are OR'ed with the
            contents of the addressed memory location. The high-order bits
            of the accumulator are OR'ed with all zeroes; therefore, the
            upper half of the accumulator is unaffected by this
            instruction.
