Where is the maplist built-in predicate ?

[spam . spam . spam . spam]

Hello,

I am using GNU Prolog 1.3.1.

I use this code :

% int(?I) : I is an integer
int(z).
int(s(X)) :- int(X).

% odd(?I) : I is an odd integer
odd(s(z)).
odd(s(s(X))) :- odd(X).

% intzodd(?I) : I is an odd integer or zero (z)
intzodd(X) :- X=z.
intzodd(X) :- odd(X).

% listzodd(?L) : L is a list which each element is an odd integer or zero (z)
listzodd(X) :- maplist(intzodd, X).

And I don't find the maplist built-in predicate.

| ?- listzodd([z]).
uncaught exception: error(existence_error(procedure,maplist/2),listzodd/1)

Where is the maplist built-in predicate, please?

Thank you.
