a DCG compiler compiles clauses. Grammar rules are not exactly Prolog; they
have to be interpreted or compiled by Prolog before they can be 
executed. There is a DCG compiler (and an interpreter) in Pereira and
Shieber's book ("Prolog and Natural Language Processing", 1987).

It looks like a very impressive package: ML, Lisp, Prolog, Pop-11 all
bundled up. As for academic discount, i thought it was a typo. 85% discount is 
bound to lure a lot of people into it.
