Can you please explain what you mean by this? Are you talking about using the hashmap to determine which record to read next, and so to read the records in an order that is logically sequential, but physically random? If so, that is not at all like reading the records sequentially. -- Tom Marchant ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
