Thanks again. It seems to me that the functions that make up the application would all move around as a unit, and there appears to be no problem calling a function at any given time. So (to me) it stands to reason that whatever method works for locating functions should work for locating constant data (data in code space).
How do people make tables of function addresses (for instance) or tables with addresses of anything (const)? Sorry to burden you with this, but my structure eventually will have pointers to other const structures (of different sizes, but all defined at compile time) so this could get really ugly if I cannot use pointers, but instead must create one big honking structure (most of which would then be unused).
