So far, there are no cheat codes, but there are some command-line
 switches. 
 
 These are all the possible switches:
 
 LR /LEV /MUS /MSN /SKIP /NOMUSIC /VGA
 
 /SKIP simply puts you right into a level with going thru any other
 screens. 
 
 /LEV is the switch that goes to any level (but with the default
 weapon and health as if starting a new game in level 1).
 
 The syntax is:
 
 LR /LEV LEVELSMISSxx
 
 where xx is the level number.
 
 Apparently what this does is replace level 1 with the given level.
 This means that starting a new game will give the mission briefing
 for level 1 and show the "Loading Level 1" screen. Saving and loading
 saved games works just fine, but if the game is exited and restarted,
 the same command line must be used to restore a saved game.
 
 The level numbers and the MISSxx files don't exactly match up. Here's
 the table: 
 
 Number Of Levels = 11
 Level 1 = levelsmiss01
 Level 2 = levelsmiss07
 Level 3 = levelsmiss04
 Level 4 = levelsmiss05
 Level 5 = levelsmiss06
 Level 6 = levelsmiss08
 Level 7 = levelsmiss09
 Level 8 = levelsmiss10
 Level 9 = levelsmiss11
 Level 10 = levelsmiss12
 Level 11 = levelsmiss13
