This script function checks whether all characters of a specified string are written in lowercase letters. Special characters and numbers that might be used within the string are ignored. You can either define the string directly (by using single or double quotes) or use a script variable for this purpose.

"N" will be returned when the string includes at least one uppercase letter or no letters at all. "Y" will be returned when all letters of the string are lowercase letters.
