It was and (as of what I've seen remains) IP-based only.<BR /><BR />You end up using event flags (and event flag wait masks; EFWM), locks and lock resources, or ASTs or threading and semaphores or such.<BR /><BR />Not having looked at what this select() is doing, I'd look to use either (gag) event flags or locks. My preference is for locks, given scaling issues I've encountered with the EFWMs. Mon, 19 May 2008 13:11:07 GMT https://community.hpe.com/t5/operating-system-openvms/select-pain/m-p/4200290#M44029 Hoff 2008-05-19T13:11:07Z
