To convert to uppercase, subtract 32 from all characters in the range 'a' to 'z'. To convert to lower-case, add 32 to all characters in the range 'A' to 'Z'. Note that each character is mapped to a value in the ASCII character table and the difference between character 'A' (#65) and character 'a' (#97) is 32. Using binary notation, characters in the range 65 to 91 ('A' to 'Z') have most significant bits 010 while characters in the range 92 to 122 ('a' to 'z') have most significant bits 011. Therefore switching bit 5 automatically flips a character between uppercase and lower-case, providing the character is an alphabetic character to begin with.
