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.
