MVZ   (MOVE ZONES) Instruction Type:  Machine Instruction Machine Format:  SS Instruction D3 L B1 D1 B2 D2 Symbolic Format:   [symbolic name]  MVZ D1(L,B1),D2(B2)             [symbolic name)  MVZ  name1,name2   *     The zone portion (high order 4 bits) of each byte from the second operand is placed in the zone portion of the corresponding byte of the first operand field. *     The instruction moves the data one byte at a time left to right. The zone portion of the leftmost (high-order) byte of the sending field is moved first. *     The operands may overlap in memory. *     The numeric portion (low-order 4 bits) of each byte are unchanged in either field. *     The first and second operands may overlap. *     A maximum of 256 bytes may be moved.      The condition code is unchanged.
