Question $17$: Check the Checksum of a String

Write a subroutine to calculate the $8-$bit checksum of the counted string pointed to by the

register R$0$ and compare the calculated checksum with the $8-$bit checksum at the end of the

string. It should set the Z$-$ag if the checksums are equal and reset the ag if they are not.

Use the associated test file to see the string you must operate on$.$ What is listed
