<quote from HLASM V1R6 Language Reference> 5.46.4.3 Range of an ordinary USING instruction The range of an ordinary USING instruction (called the ordinary USING range, or simply the USING range) is the 4096 bytes beginning at the base address specified in the USING instruction, or the range as specified by the range end, whichever is the lesser. For long-displacement instructions, the range is the addresses between (base_address-524288) and (base_address+524287) </quote> You'll notice that the range in not addressed at all for long displacement instructions. -- Tom Marchant
