One shuts Dirmaint down for such an operation. Roughly: - DIRM USER BACKUP to create a directory in a single file (on 1DB I think) - DIRM SHUTDOWN - remove USER DIRECT from DIRMAINT"s normal disk (I don't know that by heart) - do all relabeling stuff (i.e. directory, ICKDSF, DIRECTXA and IPL)) - store changed directory as USER INIT or is it USER INPUT on a DIRMAINT minidisk - restart DIRMAINT
