A lump is an entry in a .wad file, containing data used by Doom/PrBoom.
PrBoom comes with a number of extra lumps which provide data needed by some of its new features which were not present in Doom.
The Linux version of PrBoom comes with these as a separate WAD file, prboom.wad. The Windows version has them embedded in the executable file; thy can be extracted with prboom -dumplumps prboom.wad
PrBoom also looks for a number of new lumps which can control the behaviour of levels and animations in the game.
With BOOM, you could load dehacked patches on the command line. MBF, and now PrBoom, take that one step further, by allowing WAD files to contain a dehacked patch embedded into the wad file. If PrBoom finds a lump called DEHACKED in a WAD file, it parses it as a dehacked/BEX file.
Since dehacked/BEX are horribly messy to work with, they are not discussed in this document. If you need that level of customisation, you don't want PrBoom, you want one of the Doom mods which aim for customisability, like SMMU or DosDoom.

Definition of animated textures and flats recognized
The SWITCHES lump makes the names of the switch textures used in the game known to the engine. It consists of a list of records each 20 bytes long, terminated by an entry (not used) whose last 2 bytes are 0.
|
9 bytes | Null terminated string naming "off" state texture for switch |
| 9 bytes | Null terminated string naming "on" state texture for switch |
| 2 bytes | Short integer for the IWADs switch will work in
|
The ANIMATED lump makes the names of the animated flats and textures known to the engine. It consists of a list of records, each 23 bytes long, terminated by a record (not used) whose first byte is -1 (255).
|
1 byte | -1 to terminate list, 0 if a flat, 1 if a texture |
| 9 bytes | Null terminated string naming last texture/flat in animation |
| 9 bytes | Null terminated string naming first texture/flat in animation |
| 4 bytes | Animation speed, number of frames between animation changes |
These tables are used to translate the red font characters to other colors. They are made replaceable in order to support custom palettes in TC's better. Note however that the font character graphics must be defined using the palette indices for the standard red range of the palette 176-191.
