How does one go about copying the name database from another host
(running PhaseIV) in DECnet-Plus?

NCP COPY KNOWN NODES FROM doesn't work, simply gives me a
"%SYSTEM-E-UNSUPPORTED, unsupported operation or function" message. I
am able to do a SET HOST to the target node if I specify a numeric
address for it.

(Yes I'm completely new to DECnet).
