But your result is not html. In the Arc library the arguments of the tags, like whitepage are any expression and only tag the stdout (you can redirect the output to another port). For example: (= a 1) (whitepage (= b (+ a 1)) (pr b)) And you obtain: <html><body bgcolor=#ffffff alink=#0000be>2</body></html>
