Hiya, I know this may be a very simple question but i'm just starting prolog and trying to get a grasp on it - just struggling a bit.

What I am trying to do, is use a rule such as : which_system(Component).

That will return the info on a system that is declared in a fact liek :
spec([execomp211, hard_disk(40), ram(ram500MB), processor(intel_core2_duo)]).

So if i entered : which_system(hard_disk(120)). into the console then it would return the info about that system.

I've been told to use the methods:

member1(X, [X|Y]).

member1(X, [Z|Y]):-
member1(X,Y).

But I can't seem to find anymore help than that online! I'm not asking to do this for me, jsut any pointers would bemuch appreciated

Thanks

Ah, yes, as we get closer to the end of a semester, the homework gets tougher...

You need to get familiar with Prolog lists, ex:
