just i copied below content from help.sap.com,

compare
 Compares string X with string Y:

R = 0, when the strings are equal
R = positive number i, when X is lexicographically larger than Y
R = negative number i, when X is lexicographically smaller than Y

i specifies the difference between the two strings lexicographically.

The function acts in the same way as the compareTo() method of the JDK class java.lang.String.
