Suppose that four decimal digits represented in ASCII code are located in the memory at byte locations LOC and LOC +1, LOC +2, LOC +3. We wish to represent each of these digits in the 4-bit BCD code and store four of them in a 2 bytes location (HW). The result is said to be in packed-BCD format. The rightmost four bits of the ASCII code for a decimal digit correspond to the BCD code for the digit. Write a routine that packs 2X2 four BCD digits in 2 byte of the memory.
