OK. I'm not familiar with the PIC at the machine level. I just assumed
that one could execute code out of anywhere in the machine's address
space, i.e. RAM, ROM, or flash.

Hmm, I suppose. Seems like a lot of work for not very much gain but I
suppose someone might want to do that. Not many people would go to the
trouble and those who would probably can and have.
