Define the second group of 32 ASCII character codes?
The second group of 32 ASCII character codes include various punctuation symbols, special characters, and the numeric digits. The mainly notable characters in this group include the:
- Space character (ASCII code 20h)
- Numeric digits 0 through 9 (ASCII codes 30h through 39h)
Note that the numeric digits vary from their numeric values only in the high order nibble. Through subtracting 30h from the ASCII code for any particular digit you can obtain the numeric equivalent of that digit.
