[...] PDF is not able to compute like Postscript. But it can display stuff as well. So, during evaluation of Postscript-code the pdf-commands can be created. Postscript will be interpreted every time again. PDF will be created by running the Postscript-Code and then the resulkt of the Postscript-interpretation is "frozen" into static PDF. So... ok, if you want to implement a webserver in Postscript, this would not work with PDF. Ciao, Oliver
