As your Starflight adventure evolves the Starflight Universe evolves with 

you.  The result of this evolution will be referred to as the "game state". 
The game state is saved partly in memory, and partly on disk, and is not
saved entirely to disk until you use the SAVE GAME command.  
  
As a result the game state information on the disks is incomplete until you 

issue a SAVE GAME command.  At this point, the new game state is saved 

intact to the PLAY disks, but it is IMPORTANT to make a backup copy of this 

game state.  Use Diskcopy to make backup copies of both the PLAYA and PLAYB 

disks to the SAVEA and SAVEB disks.

To resume a game after giving a SAVE GAME command and backing up the PLAY 

disks to the SAVE disks, re-insert the PLAY Disks and type "STARFLT".

If you need to restore to a previous game state (because your crew got 

killed) use Diskcopy to copy from your SAVE disks onto your PLAY disks and 

then resume playing on the PLAY disks.
 
Using these precautions will ensure that you can always return to your last
saved game state.  NEVER USE YOUR MASTER OR SAVE GAME DISKS TO PLAY 

STARFLIGHT.
