It is desired to write a subroutine in PIC$18$F assembly language to compute

$Z=x1+x2+x3+$dotsdots..$+x8$

Assume the $x_i^{\text{'}}$ s are unsigned $8-$bit and stored in consecutive locations starting at $050.$ Assume FSR$1$ points to the Xi's. Also, write the main program in PIC$18$F assembly language to perform all initializations $($FSR$1$ to $030,$ STKPTR to $5),$ call the subroutine, and then compute $\frac{Z}{8}.$ Discard the remainder.
