I'm aware that OSLib provides C functions for most (if not all RISC OS swis).

Would I be better off migrating to OSLib or should I stick with my current methods. I've been told that larger and slower programs can be compiled as a result of using OSLib, I haven't varified this.

I would appreciate your views on this matter.

I guess programs may be bigger because you have to link all those specific veneers to your code. Whether it makes much difference I don't know because I don't use it. I do know that a lot of people think it's great and it does provide type-checked SWI calls.
