p_string IN VARCHAR2)
RETURN typevar50
IS
v_string LONG DEFAULT p_string || ',';
v_data typevar50 := typevar50();
v_position NUMBER;
BEGIN
LOOP
EXIT WHEN v_string IS NULL;
v_position := INSTR(v_string, ',');
v_data.extend;
v_data(v_data.COUNT) := LTRIM(RTRIM(SUBSTR(v_string, 1, v_position - 1)));
v_string := SUBSTR(v_string, v_position + 1);
END LOOP;
RETURN v_data;
END;
FUNCTION inlist(

typevar50 is a Nested Table Type. The TABLE operator is used to treat this Nested Table Type as a regular table
SQL> create type nt as table of varchar2(10)
  2  /
Type created.
SQL> declare
  2      n nt;
  3  begin
  4     n := nt();
  5     n.extend(3);
  6     n(1) := 'Test1';
  7     n(2) := 'Test2';
  8     n(3) := 'Test3';
  9     --
10     for rec in (select *
11                   from table (cast (n as nt))
12                )
13     loop
14        dbms_output.put_line (rec.column_value);
15     end loop;
