Symbol for indicating that the line actually continues

[Lars Vogel <lars.vogel@googlemail.com>]

Hello,

As the program code in my Books is sometimes to long, I have to break the line into two. I do this manually and its working fine. 

I would like to use a special sign to indicate that the line continues. I have seen printed documents where a little arrow was used. 

Does the bookbook standard has a tag for "this line continues in the next line"? If not what is the symbol which is typically used? 

My output is PDF via FOP.

Best regards, Lars
