Which means that only one is actually running instructions at a time. As opposed to running his transactions in an OTE environment, where multiple transactions can run on separate TCBs and thus on separate engines simultaneously. -- John ---------------------------------------------------------------------- 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
