Phase IV is 2.0.0. I am assuming this is Phase V messages because there has been talk about this recently. Does anyone have a link to the Phase V Routing Specification? The specs for OSI were huge. Will this link help you any? http://bitsavers.trailing-edge.com/pdf/dec/decnet/EK-DNAPV- GD_DECnet_Phase_V_General_Description_Sep87.pdf Thanks for the link. I had a quick look. It does not go into the details of the message formats, but it does say it interoperates with Phase IV, so I just wonder if it was sufficient for me to accept Phase V messages as if they were Phase IV and just ignore the version bytes. I might just give that a quick go, which host is Phase V on HECnet now? Other that this, you're best bet would be the DECNET Documentation. It should all be on-line at http://HP.COM/go/OpenVMS. Looking at the docs here: http://h71000.www7.hp.com/doc/decnetplus.html it would seem that there are no docs on the routing specification. Regards Rob
