You can make use of user defined objects in Oracle 8 onwards. You can create either table of objects or varray of objects.

I am giving you an example of using array of Record


DECLARE
-- declaration of Record
TYPE REC1 IS RECORD (COLUMN1 VARCHAR2(10),
COLUMN2 DATE) ;
-- Array of Record
TYPE TAB1 IS TABLE OF REC1 INDEX BY BINARY_INTEGER ;
TAB2 TAB1 ;
-- New Procedure
PROCEDURE P1 (TAB3 TAB1) IS
BEGIN
FOR I IN 1..10 LOOP
DBMS_OUTPUT.PUT_LINE(TAB3(I).COLUMN1||'-'||TAB3(I).COLUMN2) ;
END LOOP ;
END ;

BEGIN
FOR I IN 1..10 LOOP
TAB2(I).COLUMN1 := I ;
TAB2(I).COLUMN2 := TO_DATE('23/05/2003','DD/MM/YYYY') ;
END LOOP ;

P1(TAB2) ;

EXCEPTION
WHEN OTHERS THEN
DBMS_OUTPUT.PUT_LINE(SQLERRM) ;
END ;

I am assigning some values to array and passing it to an procedure and printing the value . The printing procedure
can exists separately also . Hope this solves your issue .
