Honestly, you should not be planning on doing this kind of thing (editing the directory source directly).
Once DIRMAINT has control, you're much better off letting it do it's thing, and making your changes transactional. You stand a very good chance of shooting yourself in the head by messing with the directory file outside. I can say from experience: you WILL mess up, and you WILL regret it. There's nothing that you can't change in a directory entry via DIRM commands these days, and the more human intervention you introduce, the more you increase the probability of hurting yourself badly. Let DIRMAINT do it's job.
