this is the part that has the generic array

FUNCTION InArray IS NEW In_Array_Generic (
      ValueType => CatType,
      IndexType => Integer,
      ArrayType => CatArrayType);

that is the call to the function so it is the first choice i first get
the 3 values with a loop

 FOR I IN 1..5 LOOP
      Get (Cats(I));
   END LOOP;
where get is a function that
Get(Cat.Id)
Get(Cat.Age)
Get(Cat.Lives)

and the 3 values are stored into one index of the array
i hope this helps and thanks
