Cheat:
 The sound and mastermind puzzles in LATEX change with 
 each game. The one for each door will remain constant, 
 however, so you can use the same one to enter that door 
 a second time. Below are special codes which can be used 
 to by-pass the puzzles.
 
 Sound Code ByPass:
 Press and hold down CTRL and SHIFT. Click on the AUDIO 
 button (located on the control panel) - the computer will 
 beep. Still holding down CTRL and SHIFT, click on the 
 ENTER button (on the security panel).
 
 Mastermind Number ByPass:
 Hold down the ALT key and click on the ENTER button 
 (on the security panel).
