  42 **  Self Destruct Sequence
  43 **
  44 **      The computer starts up the self destruct sequence.  Obviously,
  45 **      if the computer is out nothing can happen.  You get a countdown
  46 **      and a request for password.  This must match the password that
  47 **      you entered at the start of the game.
  48 **
  49 **      You get to destroy things when you blow up; hence, it is
  50 **      possible to win the game by destructing if you take the last
  51 **      Klingon with you.
  52 **
  53 **      By the way, the \032 in the message is a ^Z, which is because
  54 **      the terminal in my office is an ADM-3, which uses that char-
  55 **      acter to clear the screen.  I also stick in a \014 (form feed)
  56 **      because that clears some other screens.
  57 **
  58 **      Uses trace flag 41
