"Words Used" changes from PIC to PIC

Hi JDG,

Thanks for the information.

I tried your little experiment using the most frequently used variables but it did not change anything for me (both for F877 and F628A, there is no change).

Well, I suppose it might also have to do with how many variables you are using in the first place. If you use more than what will fit in BANK 0, then you'll never see a difference in code size.
If your program is really short, try forcing all the variables to BANK 0, then try forcing them all to BANK 3 (or another BANK). You should see a difference.
Again, if you read the memory organization section of the datasheet and compare that to how different areas of ram and code space are accessed, you'll see what I mean.
By the way, none of this code space stuff works with the 18F series of PICs. Practically everything can be addressed with one instruction on those.
