Could you get any milage out of parsing this text?

   program print_primes(output);
     const m=1000;
           &lt;ptr target="constants"/&gt;;
     var &lt;ptr target="vars"/&gt;;
   begin
       &lt;ptr target="print-m-primes"/&gt;
   end.

If so, might you parse the serialization of the content of scrap?

                                        Be seeing you,
                                          norm
