Used by the routines at OILED_ROBOT and SCENE_TOOL.

Reached when the scene after a game ends (SCENE_TOOL, OILED_ROBOT). Clears from WIPE_COUNT to the end of the object records, so the seed, the turn counter, the control method and the random number carry over, and falls into the setting up of a game at MAIN_NEW_GAME, where START joins.

A new game builds the drawing tables, has five lives, 6000 light years, and no room played yet; stirs the last game's turn count into the seed; clears the screen and shows the menu (MENU); plays the start tune; puts the robot in one of four start rooms (NEW_GAME_START); deals the valves and extra lives to their places (INIT_SPECIAL_OBJECTS); and gives every room back its colour (RESET_ROOM_COLOURS), undoing the white of the chambers activated last game.

Then three loops, one inside the other, each with its own entry: MAIN_NEW_LIFE starts a life (NEW_LIFE) and falls into MAIN_NEW_ROOM, which builds the room he is in (ENTER_ROOM) -- leaving a room comes back here from EXIT_LOW_U -- and falls into MAIN_NEXT_TURN, the start of a turn. MAIN_NEXT_OBJECT runs one record's update routine: the stack is reset to MIRROR_TABLE for every object, the address of OBJECT_DONE is pushed for the routine's RET to go to, and the record's last drawn size and place are kept (+18 to +1B into +1C to +1F) so that its old picture can be wiped. MAIN_DISPATCH jumps through UPDATES by the graphic; JUMP_THROUGH_TABLE jumps through any table of words by the index in L and the table in BC, and CALC_PLYR_DUV and SORT_AND_DRAW use it too.

Knight Lore's main and its object walk, with the clock where the sun and moon were and nothing for the cauldron; the stack is Alien 8's own, above the screen buffer, where Knight Lore's is below its variables.
