Hi Keith,

On the PIC16F877 an array can only be 96 bytes.
I believe that's the amount of RAM in one bank.
I'm not sure how the memory on the 12F675 is organized.
If you have more than one bank (I doubt it) you should be able to create one array that holds as many bytes as are available in that bank. The other bank will be used for your program's variables and overhead created by the PBP compiler.
It's going to be tight to be sure.
If there is only one bank then you are simply going to have to feel it out for yourself.

Cheers.
