Hello Phil, Thanks for the info.
Firstly I know that CPACF is not a co-processor. I guess my confusion lies in the fact that we have two Crypto Express2 features, so I am also assuming that you can also have a number of CPACF facilities. You answer suggests that I should think in terms of numbers when it comes to CPACF, and just accept the fact that: "CP Assist for Cryptographic Functions is implemented on every processor" regards ---------------------------------------------------------------------- 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
