*2: The conditions under which character string comparisons can be made are as shown below:
• Match:
• Larger string: If character strings are different, determines the string with the largest number of character codes.
• Smaller string: If the character strings are different, determines the string with the smallest number of character codes.

All characters in the strings must match
If the lengths of the character strings are different, determines the longest character string.
If the lengths of the character strings are different, determines the shortest character string.
