What "inter record gap"? Remember that 99.999% of all DASD out there is really FBA behind the scenes. There is no "inter record gap" unless you are still running SLEDs. Also remember that anybody using the STK DASD that does that funny mapping (log structured?) is going to be surprised that the backend may still have the raw data on it because rewriting a track allocates a new physical track and does not overwrite the old data. -- John McKown Senior Systems Programmer UICI Insurance Center Information Technology This message (including any attachments) contains confidential information intended for a specific individual and purpose, and its' content is protected by law.
