Uppercase Text

Uppercase characters are capital letters; lowercase characters are small letters. For example, box is in lowercase while BOX is in uppercase. The term is a vestige of the days when typesetters kept capital letters in a box above the lowercase letters. A program that distinguishes between uppercase letters and lowercase letters is said to be case sensitive.
