This SWI reads information about a chunk from the chunk directory. If the chunk is a loader, RISC OS also loads it. Copies of a module's name and help strings are held in the Expansion Card Manager's workspace, and will become invalid after the next call to it.
Note that the last valid chunk entry will still return a non-zero number for the next chunk - when this SWI is called again with R0 >= this number it will return R0 = 0, signifying the end of the chunk directory.
