I have created a"game" that will test your text processor code. Quest code is checked to some degree as you go a long, and you will see red text if it makes no sense to Quest. However, anything in a text string is just assumed to be fine. And given text processor directives can be nested, you can have some quite complicated code buried in there.
Post your code (just the text or the whole script) into the text area, and it will tell you if the curly braces, parentheses and angle brackets all match up (to some degree; it is not perfect).
