String Case Change Functions

Change the case of a string.

The String case change functions allow you to change the case of a String. They work just as their names imply.

toUpperCase()
changes the whole string to upper case characters, and
toLowerCase()
changes the whole String to lower case characters. Only the characters A to Z or a to z are affected.
