Strings can be formatted to your liking using formatting characters. Some of these characters also work to format files created in PERL. Think of these characters as miniature functions.

Character	Description
\L	Transform all letters to lowercase
\l	Transform the next letter to lowercase
\U	Transform all letters to uppercase
\u	Transform the next letter to uppercase
\n	Begin on a new line
\r	Applys a carriage return
\t	Applys a tab to the string
\f	Applys a formfedd to the string
\b	Backspace
\a	Bell
\e	Escapes the next character
\0nn	Creates Octal formatted numbers
\xnn	Creates Hexideciamal formatted numbers
\cX	Control characters, x may be any character
\Q	Do not match the pattern
\E	Ends \U, \L, or \Q functions
