Hi,

I'm trying to update some old prolog (18 years or more old!). I've
come across a predicate con/3, but can't find any documentation on
it. Can anyone help with a definition?

Thanks

Simon

Just a guess, but maybe it's related to the fundamental
Lisp function cons ("constructs") that adds a first
element to a list. In Prolog one could define cons/3:

cons(H,T,[H|T]).

It's LPA Prolog version 3.15 June 1990. I said it was pretty old :)

Thanks
