Explanation:
1. The ASCII code in S is converted into the binary-coded decimal number, and the conversion
result is stored in D.
2. The operand S used in the 16-bit instruction occupies two word devices, and the ASCII code in
S should be within the range between 0000 and 9999. If S is a string, the string should be
within the range between “0” and “9999”.

3. The operand S used in the 32-bit instruction occupies four word devices, and the ASCII code
in S should be within the range between 0000000 and 99999999. If S is a string, the string
should be within the range between “0” and “99999999”.
