I think I know what relocation is. Fixing up all the addresses in a program
is one method of relocation. Copying the code before it's executed is
another form of relocation. Because when you are copying it, you are
"relocating" it, it is then located in a different area in ram.

Yes. They are. Therefore they HAVE to be at that address when run,
otherwise they will most likely not work (they will work if they have no
fixed addresses refering to themselves). What I was saying is that I
thought that ION relocated programs to this address (yes, we know it does,
otherwise nothing would work), but that the TI-OS did not.
