I have a quick question about using p2 as a pointer when accessing external data through r0 or r1.

I have three tables that I am working from at a time. Data is taken from the first table (keyboard scan code), converted using a second lookup table (converted to hex), then stored in a third table (to use half the space in permanent storage), I am using dptr, r0, and r1 for this. My question is, do I need to move #80h into p2 every time I use r0 and r1 or will using dptr change p2?

If I have not been clear, please feel free to ask me to clarify my question.

Thanks for your help!
