convert script to PL/SQL procedure

convert script to PL/SQL procedure

I am new to Oracle PL SQL. For following script, how to make it a
procedure? I need to convert the script below to a procedure so that I can
call it from an application (SSRS 2005). The application use Oracle client
driver and can't run the script below but can run procedures. So I am
thinking to convert the script to a procedure.
If without the Exec dbms_application_info.set_client_info('81'); The
script can be run by the application no problem. Although I can run it in
Toad no problem.
Exec dbms_application_info.set_client_info('81');
SELECT
ooh.order_number Order_number
, ool.ordered_item
,ooh.ordered_date
FROM apps.oe_order_headers_all ooh
, apps.oe_order_lines_all ool
WHERE 1 = 1
AND ooh.header_id = ool.header_id
AND ooh.order_number = '27889292'
--AND ooh.ordered_date BETWEEN TO_DATE('28-FEB-2013
00:00:00', 'DD-MON-YYYY HH24:MI:SS') AND
TO_DATE('28-FEB-2013 23:59:59', 'DD-MON-YYYY HH24:MI:SS')--
1.3
and ooh.ordered_date >= TO_DATE('28-FEB-2013 00:00:00',
'DD-MON-YYYY HH24:MI:SS')
and ooh.ordered_date < TO_DATE('01-MAR-2013 00:00:00',
'DD-MON-YYYY HH24:MI:SS')
