The contents of this register are modified with eitherthe zone modifying digit fJ or the zone portion of the rightmost character inthe specified register.fJ Zone modifying digit: The digit (hex O-F) followed by hex 0, or the addressof the decimal register that contaiJ1s the modifying digit.II Length: The number minus 1 (hex O-F), of bytes to modify.II Displacement: The offset (hex O-F) into the result register of the leftmostbyte to mod ify .The bytes of the decimal result register (Ra) are modified, starting at the bytespecified by offset and continuing to the right for the number of bytes specified bylength. The hex character specified by the operand replaces the original zone ofeach byte specified. If the offset plus length exceeds 16 bytes, the bytes of thenext register are also modified.164
