Extracted text: A set of eight data bytes is stored in memory starting at XX50 H. Write a program to add two bytes at a time and store the sum in the same memory locations, low-order sum replacing the first byte and a carry replacing the second byte. If any pair does not generate a carry, the memory location of the second byte should be cleared.
