[Xerte] Escape sequences

[Marc Torruella Altadill]

Hi Fred,
What i use to use is \r\n, dunno why, just done it all my programming life
:-).
If you wanna know the difference between \r and \n check what I found:

Source: http://www.htmlcodetutorial.com/help/ptopic1794.html

\n is a new line and \r is a carriage return

Asunto: [Xerte] Escape sequences

Just a couple of very minor queries, not problems, honest:

1. In the app I'm working on, put together by someone else (see prior
email), there's the following code:

  summary += texts[i] + '\r\r';

I take it that \r is an escape sequence, but what for? The two \r seem
to generate a new line, but I'd have expected \n for that. Is there a
help topic on the escapes available in Xerte?

2. In a text icon the text simply reads:

{summary}

which displays a text variable built up in a previous script icon. If I
add anything else to the text then the var ceases to display and I just
see the string "{summary}". What are the rules for using this construct?

Just minor curiousities, no big, feel free to ignore :)

Cheers
