Quintus to Gnu Prolog conversion

[Pauline Kra]

We have been running our parser with Quintus Prolog and wish to replace Quintus with Gnu Prolog. But the Gnu compiler finds syntax errors such as the ones below. I shall warmly appreciate suggestions for correcting the errors, and any information where a comparison of Gnu Prolog syntax to Quintus Prolog can be found.
