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