MUSINFO

MUSINFO is a lump originating from Risen3D and also supported by PrBoom+. It is used to associate music lumps to numbers, which are then referenced by MusicChanger things.

The syntax is as follows:

<MAPNAME>
<number> <MUSICLUMP>
<number> <MUSICLUMP>
...
<MAPNAME>
<number> <MUSICLUMP>
<number> <MUSICLUMP>
...
etc.

For example:

MAP01
1 D_ROMERO
2 D_STALKS
MAP02
1 D_RUNNIN
7 D_MESSAG

The value 0 is reserved for the map's default music. Maps in Doom format are limited to numbers in the 1-64 range; which is probably already more than needed in most cases. Other map formats have a higher limit or no restriction, and ACS allows to use more complex functions to change music through SetMusic and LocalSetMusic.
