You could just patch the system. :-) $SYSNM is where the name is, unless I remember wrong. Check the address in the map, and then ZAP the .SYS image. (And/or open the memory locations on the running system, and change the value.) Also, DECnet can change the name of a running system. But no, there is no command that does it for you.
