prolog::nth0/4¶

nth0(? N, ? List, ? Elem)*

True when Elem is the Nth member of List, counting the first as element 0. (That is, throw away the first N elements and unify Elem with the next.) It can only be used to select a particular element given the list and index. For that task it is more efficient than member//22.
