  48 **  Self Destruct Sequence
  49 **
  50 **      The computer starts up the self destruct sequence.  Obviously,
  51 **      if the computer is out nothing can happen.  You get a countdown
  52 **      and a request for password.  This must match the password that
  53 **      you entered at the start of the game.
  54 **
  55 **      You get to destroy things when you blow up; hence, it is
  56 **      possible to win the game by destructing if you take the last
  57 **      Klingon with you.
  58 **
  59 **      By the way, the \032 in the message is a ^Z, which is because
  60 **      the terminal in my office is an ADM-3, which uses that char-
  61 **      acter to clear the screen.  I also stick in a \014 (form feed)
  62 **      because that clears some other screens.
  63 **
  64 **      Uses trace flag 41
