SYNTAX      DIRECT   [<LABEL>] SAR <AR><dma>
            INDIRECT [<LABEL>] SACL <AR>,{ind}[,<next ARP>]

OPERANDS    0 . dma . 127; 0 . next ARP . 7;
            0 . auxiliary register AR . 7.

EXECUTION   (PC) + 1 . PC
            (AR) . dma

DESCRIPTION The contents of the designated auxiliary register (AR) are
            stored in the addressed data memory location.

            When modifying the contents of the current auxiliary register
            in the indirect addressing mode, SAR ARn (where n = ARP)
            stores the value of the auxiliary register contents before it
            is incremented, decremented, or indexed by AR0.
