Thanks, but the section covering arrays in the manual says:
On PIC18 devices, byte, word and long-sized arrays are only limited in length by the amount of available memory. The compiler will assure that arrays, as well as
simple variables, will fit in memory before successfully compiling.
My example allocates 265 bytes and one bit, add to that the PBP system vars. It should easily fit in the 1536bytes in the 18F25K20, which is what I'm using by the way, and I'm not getting any errors or warnings.

My "index-pointers" are WORD sized (becauae I have 256*8=2048 bits in the array) but currently it looks like I can't index bits beyond the 32'nd byte (ie when the index pointer is >255). I haven't seen anyone mention this limitation so I'm not saying this is the case (and I really hope it's not) but currently it's the only thing I can think of.

Thanks!
