Martin,
you have confused me with your question. The org statements are usually
reserved for setting the positioning in ROM (the program space) and you
simply provide names (Aliases) for the actual register files. They are
paged and you need to set flags in the FSR for the data memory pages.
(Need to also flags in Status file for the paging control on program memory)
This stuff (the paged memory) is only drawback I see in the PICs.
