Luckily at the time, I was 25 and in better shape. Then I got to argue with the police lieutenant that the lock key had to be in the "on" position to use the terminal. He kept insisting that in the "on" switch the terminal was "insecure". I finally told him it was like an ignition key. If the key isn't in and "on", the car won't run. And yes, it is "insecure". > > Groete / Greetings > Elardus Engelbrecht > > ---------------------------------------------------------------------- > For IBM-MAIN subscribe / signoff / archive access instructions, > send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN > -- This is clearly another case of too many mad scientists, and not enough hunchbacks.
