I agree with Byron.  Your question leaves the impression that you don't want
to bother reading the manual and want someone just to solve the problem for
you.  I'm not going to do that.  Come back after you've done the basic
homework and have specific questions.  HINT: you can index thru memory
buffers by using indirect addressing.  This is done by use of the INDF and
FSR registers.
