Hello,

I'm looking how to ask 2 rules, I wrote in the PIE window (see below) :

Code: Select all

hypothese(A):-
    etat(B),
    etat(C).
    
hypothese(D):-
    etat(E),
    etat(F).

And I would like to write in Dialog Window, something to find "B" and "C", knowing "A" ?

I try this: "hypothese(A):- etat(Y), etat(Z)."
but it ask me for unknown clause.

May be it's not possible ? but I rather think something is wrong in my code..!

Could you help me ?

Thanks.
Jeangil
