Yes, that's clear. What always gets my knickers twisted is when you can RESET the ECB and be sure you don't lose an event. I think I've convinced myself that, in this simple ping-pong case, just testing the post bit will work. Maybe I'll run THAT test, too. This is why I prefer data parallel programming to thread parallel programming; it makes my head hurt less. -- Jerry ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
