Alain, The AppleTalk Zones example does work. However, can anyone explain HOW it works? I don't have a clue! There is almost no documentation and I can't even see where any system calls are made (_xCall???). Who can understrand this? I bet 97.2% of FB owners can't. I had hoped to learn something from this that I could build on....like next getting a list of devices on a zone. Well that ain't going to happen. Why isn't the OTATalkGetMyZone, OTATalkGetLocalZones or OTATalkGetZoneList toolbox functions used? Wouldn't that have been easier? Isn't that what those fuctions are for? Any enlightenment appreciated, Jeff-
