But other executor parameters would remain lost after a purge. Just out of curiosity, which executor parameters would you loose with 'copy known nodes'? We (Italian DECnet) usually do a 'copy known nodes from xxxxxx using permanent to both with purge' and never noticed any problems (as long as there are no "private" nodes locally defined and not registered into the node we consider the authoritative database for node names). The above works for VMS (at least down to V4.7); TOPS-10 has to be manually updated; RSTS too; I do not remember about TOPS-20 any more: too much time has passed since my last experiments with it.
