Forty-two groups of eight bytes, one group per object (including "nothing at all"). The values are:

Offset	Effect
0	Weight / flags
1	Use status flags
2	Unused
3	Read text (index)
4	Attribute flags
5	Terrain interaction parameter
6	Attribute
7	Graphic index in lookup table at 29272

Byte 0: Objects can have weight values from 0 - 15 inclusive. Weight is defined by the first four bits of the first data field. The remaining bits are for object flags:

Bit	Effect
0	Weight
1	Weight
2	Weight
3	Weight
4	Drop-status (set means cannot be dropped)
5	Can-be-read
6	Can-be-blown
7	Unused

Byte 1:

Use status is comprised of bitwise flags:

Bit	Effect
0	Unused
1	Unused
2	Unused
3	Can-be-worn
4	Unused
5	First can-be-thrown flag
6	Can-be-thrown-and-is-lethal
7	Second can-be-thrown flag

Byte 4:

Flags which each specify whether the object's attribute applies to one of the object's four constituent character blocks. This value also effectively specifies which of the four possible character blocks are occupied by the object (i.e. the object's size in characters). This is relevant to the application of the object's terrain interaction parameter. The remaining bits of byte 4 determine whether or not the object can be smelled. If any of these remaining bits are set then the object will enable the "SMELL SOMETHING" command, otherwise this command will be disabled.

Bit	Effect
0	Paint-top-left
1	Paint-top-right
2	Paint-bottom-left
3	Paint-bottom-right
4	First can-be-smelled flag
5	Second can-be-smelled flag
6	Third can-be-smelled flag
7	Fourth can-be-smelled flag
