Quick Symbol Question: Line Breaks in Strings?

Hi All,

When I am putting strings together using a variable expression component, I can use a "&" to link strings together. Is there any sort of symbol that can be used to signify a "line break" or "return" for multiline string data? Basically, I am trying to use some grasshopper to generate code (vaguely similar to what Andy Payne did with his G-Code generator), and it would be nice to be able to put different strings on different lines.

thanks for any help
