Henrik,

I don't have the definitive answer either, but I think that what Art is suggesting makes sense to me. I have tried moving to the beginning of the program subroutines that I use a lot in the program and the used programming code space is reduced by a good number of bytes. So, I assume that the program is also executing faster. I believe that this has something to do with the way the program memory is organized in pages in many PICs.
