Easy. Offer to do the following: Start with the first byte on the first disk. Convert it and the following 0-n bytes to decimal numbers. Put that number in your list of suspiscious numbers. Also unpack the same bytes to create a second set of potential numbers. Also keep the 16 byte sequence as a suspiscious number. Procede to the next byte on the disk. Repeat for the entire disk. Then repeat for all disks. Then repeat this process for every tape. You will now have a list of potentially suspiscious numbers which consumes more space than all of the disks and tapes in your shop, probably by a factor of at least 10. Print the list and send it to the requester. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
