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

57 **	Uses trace flag 41
