Zero and Add Packed


(ZAP) An IBM assembly language instruction for performing packed decimal arithmatic on the System/360 and System/370. The ZAP instruction sets the content of one location (its first operand) to zero and then adds the content of a second location (the second operand) to the first. The first location might be used as an accumulator.
