Question

I have this predicate that has about a thousand possibilities and I need all possibilities as an output. It is not possible to simply copy and paste all listed possibilities in SWI-Prolog on Windows since you can only scroll up so much.

My predicate looks like this:

?- question(X,Y,Z).
X = 'Fo',
Y = 'Ob',
Z = 'Ar' ;
X = 'Fo2',
etc...

I was wondering if there was a way to save the result in a file or something?

Answer 1

You can use something like this:

main :-
    tell('output.txt'),
    (
        question(X,Y,Z),
        writeln([X, Y, Z]),
        fail
    ;
        told
    ).

Or you can run the query ( question(X,Y,Z), writeln([X, Y, Z]), fail ; true ). in Prolog and get all solutions at standard output (screen).
