EXTEND Method

EXTEND procedure has three forms. EXTEND appends one null element to a collection. EXTEND(n) appends n null elements to a collection. EXTEND(n,i) appends n copies of the ith element to a collection. EXTEND operates on the internal size of a collection. If EXTEND encounters deleted elements, it includes them in its tally. You cannot use EXTEND with associative arrays.
