SYNTAX      [<LABEL>] BNC <pma>[,{ind}[,<next ARP>]]

OPERANDS    0 . pma . 65535; 0 . next ARP . 7.

EXECUTION   If carry bit C = 0:
            then pma . PC; else (PC) + 2 . PC.
            Modify AR(ARP) and ARP as specified.
            Affected by C.

DESCRIPTION The current auxiliary register and ARP are modified as
            specified. Control passes to the designated program memory
            address if the carry bit C = 0; otherwise, control passes to
            the next instruction. Note that no AR or ARP modification
            occurs if nothing is specified in those fields. Pma can be
            either a symbolic or numeric address.

            The carry bit C is affected by all add, subtract, and
            accumulate instructions as well as the ABS, LST1, NEG, RC, SC,
            rotate and shift instructions. The carry bit is not affected
            by execution of BC, BNC or non-arithmetic instructions.

EXAMPLE     BNC   PRG325      If the carry bit C = 0, 325 is loaded into
                              the program counter; otherwise, the PC is
                              incremented by 2.
