(Nor do I know a TOPS-20 equivalent, but I would like to...) As T10 and T20 shares the same code, the answer is the same for both: it dont have such a command. The command can be added(#63621873 on my list of things to do) but it's still not to usefull as T10/T20 do not have the concept of a permanent database for DECnet. As there are monitor calls to talk to DECnet there is a small program "NODNAM.EXE" that reads INI:NODNAMN.INI and loads the internal DECnet data structures... nodnamn.ini can have both "set" and "define" lines.. set node 1.13 name nim define node 1.13 name nim --P
