I honestly cannot believe that people are still 'optimising' CPU. Unless you call major chunks of CPU-intensive code, you are not going to find enough savings to buy a beer. I/O, even with today's faster hardware, is where you should be concentrating. Especially, on non-Mainframes. - Too busy driving to stop for gas! ---------------------------------------------------------------------- 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
