<blush> And my timing code did just that; it's such an inherent piece of the idiom that it didn't occur to me to disable the "quick POST" for this test. So my timings are, arguably, completely wrong. If I get a chance, I'll re-test. -- Jerry ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
