Defaults to the newline character (ASCII 10; '~n'; '\n'). A null string value causes a NEWLINE character (not a null string) to be output. You might want to set this to "~n" (the NEWLINE character) or to the null string (to force the NEWLINE character). Depending on the other attribute values, using the NEWLINE rather than the <BR> tag can result in more readable output when viewing document source in a browser.
