Notes
The values returned in R4 specify the status of the module.
The value -2 was added by ROL in their version of the OS, and is currently not returned by RISC OS 5. An example of when a value of -2 would be returned would be for if a podule containing a 32bit incompatible module is used in a 32bit-only system.
