discontiguous predicate

[carlos calderon]

hi all,

I've got a simple list of facts, i.e:

female(joan).
male(david).
male(paul).
female(rachel).

Well, if i try to compile this, it gives me a warning: discontiguous predicate female/1.
Ok, I can change the order of my predicate to make them "contiguous" but that's not a proper solution.
I went to the gnu_prolog manual, pag-42 section 5.1.5 and based upon that I thought this might work:
discontiguous(female).
female(joan).
male(david).
male(paul).
female(rachel).

but it didn't. I got the same warning.

Again, apologies if the question has been answered before but I am new to the list and on the steep end of prolog's learning curve.

You should do

discontiguous(female/1)

See you,

discontigous is a directive. To be executed, it must be given as a goal.
The correct text is:

:- discontiguous(female/1).
female(joan).
male(david).
male(paul).
female(rachel).
