Can be very fast and effective if you keep all the jobs swapped in and dispatched at the same rate. 32MB would be plenty for this case. ---------------------------------------------------------------------- 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
