Oracle Database Discussions

I am calling a Oracle Stored Procedure through COBOL program. Here is the procedure that is in Oracle.

PROCEDURE sp_sel_m_event_subs_profile (
eventID IN EventIDTyp,
subscribed IN NUMBER,
v_profileRef OUT profileRefWithDSID_cv
)
IS
BEGIN
sp_check_event_id(eventID);

OPEN v_profileRef FOR
SELECT
sub.profile_i,
ref.datasource_i,
ref.primary_key_x
FROM
ccf_event_subscribe sub,
ccf_profile_reference ref
WHERE
sub.event_i = eventID
AND
sub.is_subscribed_i = subscribed
AND
sub.profile_i = ref.profile_i;
END sp_sel_m_event_subs_profile ;

So while trying to call this procedure in COBOL program I am getting error as wrong number or types of arguments in call to 'SP_SEL_M_EVENT_SUBS_PROFILE'

Here is the call statement in COBOL. I tried with many other options by adding some more fields but did not work.

EXEC SQL EXECUTE
BEGIN
TWSUSER_OWN.PKG_CCF.SP_SEL_M_EVENT_SUBS_PROFILE
(:EVENT-I, :SUBSCRIBED);
END;
END-EXEC

Please someone let me know how should I pass arguments EVENT-I and SUBSCRIBED to this Procedure so that I will get PROFILE-I, DATASOURCE-I and PRIMARY-KEY-X

Note: The above procedure is working good by other software. But there is no example as How to use Call statement through COBOL.

Thanks
