I don't understand this. I'm not going to IJCAI myself. I'm not even going to be able to go to NACLP-90 (something to do with a shortage of money). Why should I give someone else plane tickets? Putting spaces after the commas that separate arguments of predicates (but not of data values) makes code *much* more readable. Commas are used for enough things in Prolog that taking professional care with them can be a big help. -- Fear most of all to be in error. -- Kierkegaard, quoting Socrates.
