Nested Tables / VARRAYS

Question

I need some suggestions on how to use an array in PL/SQL block. This is the code that I have written so far.
  parsing text in Pl/SQL.
declare
  type stc is table of varchar2(6) not null;
  v_stc   stc;
  stctext varchar2(100) := '450011450012450013';
  i       integer := 1;
begin
  v_stc := stc(100);
  While length(stctext) > 0 Loop
    dbms_output.put_line('STCTEXT -BEFORE ' || stctext);
    v_stc := stc(substr(stctext, 1, 6));
    dbms_output.put_line(v_stc);--FAIL.
    stctext := substr(stctext, 7, length(stctext));
    dbms_output.put_line('STCTEXT -AFTER ' || stctext);
    i := i + 1;
  End Loop;
end; The objective of this code is to split the stctext into strings of 6 characters each and populate the strings in an array.
Any help would be appreciated.

Why don't you go for SQL solution?
Anyway,
Your solution still needs to fixed even if we patched the output statement ->
