Initialize 2 dimensions arrays

Question

Hi everybody.
Im using Oracle 11g, on Linux Centos.
My problem is with 2 dimensions array.
I have defined a type in the database in this way :
create or replace
TYPE ARRAY_N_12 is varray(12) of number;
Now I try to do the next :
create or replace
procedure PRUEBA_INDEX as
  type xyzp is table of array_n_12 index by varchar2(5);
    XX xyzp ;
  I number;
  Z number;
begin
   for I in -1 .. 100
   LOOP
   for Z in 1 .. 12
   LOOP
     XX(I)(Z) := i;
   end LOOP;
   end LOOP;
  and follow other commands.
When I compile this it do it without errors. But when I try to run it it say me error :
ORA-06531 , not initialized recompilation.
I understand that I need initialized the array. But I dont find the way.
If I do the next :
xx xyzp := xyzp(); It say me no valid in this context.
so I have been trying another ways but I dont find.
Can anybody help me with this?.
Thanks in advanced & regards.

Mixing VARRAY and INDEX BY collection types doesn't make this any easier to follow.
FOR i IN -1 .. 100 LOOP
   -- initialise element
   xx(i) := array_n_12();
   FOR z IN 1 .. 12 LOOP
      -- extend element
      xx(i).extend;
      -- assign element
      xx(i)(z) := i;
   END LOOP;
END LOOP;
