A FIND_RECORD table of 61 objects, whose values are the objects' own records. The keys come in two runs: $00 to $2B without a gap, then $3C to $4C. The second run is the characters -- every one of the nine seen wandering in a single turn had its number here, and ACTING, which says who a sentence is about, holds numbers from that same run. So a character is an object with a number in the upper block, not a separate kind of thing.

Object 0 is the player: ACTING, which is zero when a sentence is about you, holds object numbers, and object 0's location is where the player is.

A record is a 16-byte head, then the locations the object is in -- byte 0 of the head says how many -- then its own action handlers (see FIND_OBJECT_HANDLER). Watched rather than inferred: over several turns the one byte that changes in any character's record is the first of those locations, as it wanders; and when the player walked east out of Bag End and back, object 0's location went 1, 4, 1, matching at every step the location whose picture DRAW_LOCATION_PICTURE looked up. Most things are in one place; the ones in several are fixtures between rooms. Object 5 is in locations 1 and 4 -- exactly the two rooms that walk went between, so it is the round green door.

The head, as far as it is known. Byte 1 is what holds the object or has it inside, $FF for nothing: see SHUT_IN. Byte 2 is its size and byte 3 its weight, and for a character byte 3 is the most it can carry: the routine at CAN_LIFT compares a thing's weight and load with the actor's byte 3 and fails with "is too heavy to lift", the one at GIVE_TOO_MUCH with "you are carrying too much", and the one at DO_CLIMB_INTO_1 compares the actor's size with the room in the thing at byte 2 and fails with "you are too big". Doors, walls and fixtures are $FF in both. Bytes 14 and 15, where not zero, are the object's own description: the map's says there seem to be symbols on it that you cannot read, printed through RUN_MESSAGE. Byte 4's low four bits say how things are placed with this object, as PLACED_WORD prints it: 0 in, 1 on, 2 behind (the curtain, which the wall is behind), 3 under (the trap door), 4 tied to (the rope). Its bits 4 to 6 are sides (see SAME_SIDE): 1 for the player, Gandalf, Thorin and Bard; 2 for Gollum and the goblins; 4 for the wood elf and the butler; 5 for Elrond, on two; bit 7 is on the window alone. Byte 5 is strength and byte 6 defence, what DO_ATTACK weighs, and both wear down with wounds -- and a fall in the dark halves the player's strength.

Byte 7, the flags. Bit 7: there, to be seen and reached -- IN_REACH wants it, and the only two objects without it are the mountains' side door, which is secret, and the butler. Bit 6: a character -- set on the player and the seventeen others, objects $3C to $4C, and on nothing else, and what FIND_NAMED_OBJECT's mode picks on. Bit 5: can be seen into, which SHUT_IN climbs through; the characters have it, and the goblins' cache and the wooden boat. Bit 1: a liquid -- exactly the wine and the four waters, and the rivers. Bit 2, on a container, is full: DRINK and EMPTY clear it, and FILL will not fill what has it. Bit 3 is dead, or broken: KILL sets it on a character, and a struck spider web has it until it is mended. Bit 4 gives light: it is on exactly the sword and the torch, and nothing else, as Wilderland also has it. Bits 2, 3 and 4 together are what TOO_DARK reads on the sword; the torch has the same flags. Bit 5 is also a door's being open: OPEN sets it and CLOSE clears it, and CAN_PASS will not let anyone through a way whose object has neither it nor bit 3. Bit 0 is locked: LOCK sets it and UNLOCK clears it, and it is on four doors to start with.
