...character.^7.2

The character that follows a ``\'' might be special. One we have been using is ``\n'' which, inside double quotes, tells perl to move to the next line on the page or on the screen. In order to be able to print a ``\'' without worrying if the next character is an ``n'' perl uses ``\\'' inside the double quotes. See http://www.bobbemer.com/ESCAPE0.HTM
