Thanks Radoslaw & Bob. I figured there must be some explanation for the additional byte other than some new extended device ranges.
This is still a DOC problem as the manual simply states these are device addresses. Radoslaw, are you saying there is a way of creating an IPLable device with a 5 byte device address after z/OS 1.7? How is that possible when UCBCHAN only provides space for 4 byte addresses (which "D U,..." uses)?
