Actually I don't do that, because I prefer PBP to position it's internals for itself. If you start using ORG then you could, potentially, run the risk of having PBP create code that could intrude into your reserved space. All I do is workout the address of the start Label (in my previous example 'Setups:') and reference everything from that starting point. The added advantage is that all the reports for BYTE or WORD usage for your PIC take into account your Reserved Space and you get a better feel for how you're filling your PIC up. If you decide you are going to use ORG and position your reserved space up in high memory (nothing stopping you doing that), then you don't get a clear idea of how big your PBP code is, and how much you've got vacant before you intrude into your reserved space.

And before you turn around and ask "How can I work out how to get the address of a Label?", let me refer you to a three-year-old thread...
