I just gave a presentation to our user community about the z10 BC → z14 ZR1 upgrade we did last August. One of the most challenging things about this upgrade was our z14 has zIIPs, which we didn’t have before. But try explaining zIIPs and CP capacity levels, or processor characterization in general! Those are totally irrational, except in the context of how mainframe software is priced. -- Pew, Curtis G curtis....@austin.utexas.edu ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
