I have been trying a few of your example programs but with little success. I am using Sicstus 3.7 and have tried some of the suggestions made already such as changing the html.pl (Alexander Serebrenik 06/13/99) and used a shell script to control my programs. I have run the make file as instructed in the README. When I try to access the cgi script via a browser I get an Internal Server Error. When I run the files in a shell tool I get the following hades{c9651239}6: html_forms.cgi SICStus 3.7: Tue Sep 08 19:55:50 MET DST 1998 Licensed to hud.ac.uk {SICStus state restored from /stud/yrf/bsccsd4/c9651239/pillow/pillow/examples/html_forms.cgi} Content-type: text/html html.pl Error Report

html_pl Error Report

The following error was encountered: existence_error(main,0,procedure,:(user,/(main,0)),0)

I have checked everything I can think so I wondered if anyone had any ideas.

In order to solve this problem you should redirect the stderr to /dev/null when you run html_forms.cgi, so sicstus loading messages ignored and your browser see "Content-Type text/html" first. (2) The existence of main/0 you already got an answer from daniel for this. > hades{c9651239}6: html_forms.cgi > SICStus 3.7: Tue Sep 08 19:55:50 MET DST 1998 > Licensed to hud.ac.uk > {SICStus state restored from > /stud/yrf/bsccsd4/c9651239/pillow/pillow/examples/html_forms.cgi} > Content-type: text/html > > html.pl Error Report >

You either has misspelled the name or you have compiled the file as a module instead of a user file. .......................................................................... : : Facultad de Informatica : : Daniel Cabeza Gras : Universidad Politecnica de Madrid : : CLIP Group : 28660-Boadilla del Monte, MADRID : : dcabeza(a)dia.fi.upm.es : SPAIN : .......................................................................... --===============2888925272974685524==--
