Thanks for the correction. But, from your comments, I would take it that the System z is simply not worth using, except for z/OS (maybe z/VSE) legacy work. If this is true, then I see no reason why any company would get a z for new work. And, if a company could move its workload from, say, CICS to WAS, it would be less expensive to run that work on Intel. Not a nice picture. But, with any luck, I'll die of a massive coronary before I lose my current job (and the economy is getting bad enough that that is becoming more of a probability). -- 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
