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