We don't do updates automatically these days.  To really affect Grapevine requires issuing the GVUpdate command (registered by NamesAndLog.bcd) manually.  It will write all dirty entries, so use the flush operation judiciously.
IF update THEN NamesGV.GVUpdate[rName];
IF update THEN NamesGV.GVUpdate[rName];
NamesGV.GVUpdate[rName];
IF update THEN NamesGV.GVUpdate[rName];
NamesGV.GVUpdate[larkRname];
