An insanely detailed code sheet.  Can you imagine what it was like to 
have to sit down and decide on all these messages?  And then prioritize 
them by deciding to make some easier to send than others.  Q-I-Q-I is 
scary.  I hope I never have to send J-V-J-V or, for than matter, anything 
in the vein of Q-Q-Q-Q.
