Considerable coding; much to learn if you haven't used it before; but it's effective. Each child (I don't believe you can do 5000 at once), could write its report to a separate file, and when all complete the master could merge, catenate, or summarize them. -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN MARKSANDSPENCER.COM ________________________________ Unless otherwise stated above: Marks and Spencer plc Registered Office: Waterside House 35 North Wharf Road London W2 1NW Registered No. 214436 in England and Wales.
