Is it Friday yet? The z13 (I think) added this puppy:
========================= LOAD AND ZERO RIGHTMOST BYTE The second operand, with the rightmost byte set to zero, is placed at the first-operand location. For LZRF, the first and second operands are 32 bits, and for LZRG, the first and second operands are 64 bits. The displacement is treated as a 20-bit signed binary integer. It is unpredictable whether an access exception is recognized for the rightmost byte of the second operand. ========================= Why? -- Jerry ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
