Hi

I'm new in prolog and have some easy question:

1- How can I create a file in prolog?

2- How can I read from a file or check that, say "john is father of
bob" (father(john, bob)), from that file?

3- How can I write a new predicate in the created file
(e.g. father(jim, alice).)?

Many Thanks
Steve
