**  INSTRUCTION READ AND MAIN PLAY LOOP
**
**      Well folks, this is it.  Here we have the guts of the game.
**      This routine executes moves.  It sets up per-move variables,
**      gets the command, and executes the command.  After the command,
**      it calls events() to use up time, attack() to have Klingons
**      attack if the move was not free, and checkcond() to check up
**      on how we are doing after the move.
