Because there are not system APIs for everything, nor should there be.

As an example, there have been a few times in recent memory that
someone asked about doing the equivalent of XOR and other bit
operations from RPG.  We both know this is trivial at the machine
level, but there is certainly not a system API for it, nor is it in
the C function library because it doesn't need one!

I _knew_ there had to be a simple way to do, but without the MI
Functional Reference manual I couldn't know how to code it.  Barbara
piped in with prototypes to the MI functions.  

Just having the documentation on stuff like this, or _memcpy or
whatever, opens a new realm of possibilities from RPG IV.
