Text Parsing

I hope somebody can help me with this, i'm sure its quite simple, I am trying to use John Percivils String parsing program from teh projects part of this site, I have been playing with it and am trying to get it to recognise a carriage return, bu to do this i have to enter it into a string, The question is what is the sign for a carriage return? I know if it parses a paragraph of text, it displays the returns as a thick verticals bar, but how to i put this symbol in the string?

Any gratefull of any help

Cheers in Advance

Andy
