toUpper() function

The toUpper() function returns a string, converting any lowercase letters in the original string to uppercase. The syntax is as follows:

toUpper(<string>);

The following script assigns the first letter of each word to the variable a. The a variable is concatenated with another variable, name, to form an acronym. The toUpper() function capitalizes the entire acronym before it is printed.
