The comparison of the size of alphabetic characters in computers is generally based on "ASCII codes". Alphabetic character comparison refers to the operation of comparing the size of a single character or string according to dictionary order, which is generally based on the size of ASCII code value as the standard of character comparison.

In a microcomputer, character comparison (character comparison) refers to the operation of comparing the size of a single character or string according to dictionary order, usually based on the size of the ASCII code value as the standard of character comparison.

If the ASCII code value of one character is greater than the ASCII code of another character, the previous character is considered to be "greater than" the next character, such as "C" is greater than "A".

The characters generally use the ASCII character set commonly used in the world. Each character is represented by an 8-bit binary code inside the computer. BASIC stipulates that the comparison of two single characters is the comparison of their code values. For example, in the ASCII character table, the code value of "A" is 65 (decimal number) and the code value of "B" is 66 (decimal number), so "A" is less than "B". When the operation "A"
