2.2
Character string comparison
Characters can be compared with the same relational operators as used for numeric values.
Character string comparison can be used to find out the contents of character strings, or to sort
character strings into alphabetical order.
■
In the case of character strings, the comparison is performed from the beginning of each string,
character by character.
■
If all characters match in both strings, they are considered to be equal.
■
Even if only one character in the string differs from its corresponding character in the other string,
then the string with the larger (higher) character code is treated as the larger string.
■
When the character string lengths differ, the longer of the character strings is judged to be the
greater value string.
All examples below are "true".
Examples: "AA"<"AB"
"X&">"X#"
"DESK"<"DESKS"
