Parameter queries in Oracle?

Question

Does Oracle allow for queries that receive a
parameter from ADO? The ability to call
pre-compiled queries is very powerful in SQL
Server. I would like to use the same in Oracle,
but I don't find any reference in the documentation.
Any help will be appreciated, Tony.

I thought I give you the details.
The Package (ITEM_CLIENT) looks like this:
AS
TYPE outputCursor IS REF CURSOR;
PROCEDURE Client_Return (ClientID IN NUMBER OUT ItemClient.outputCursor);
END ItemClient;
When I click over Edit Package Body I see:
IS
PROCEDURE Client_Return (ClientID IN NUMBER,
Clients OUT outputCursor)
AS
BEGIN
OPEN Clients FOR
SELECT * FROM Clients
WHERE Client_ID = ClientID;
END;
Finally, when I click Compile I get the error:
Encountered end-of-file when....
I find it very confusing to deal with packages and
stored procedures. I understand the concept of package
and I like the idea of being able to group all
associated stored procedures in one package, but I am
having a hard time associating the stored procedure
with the package. I read the documentation on PL/SQL
and followed the syntax spelled out there (and as
provided by you), but I have yet to still cannot
create a simple stored procedure I can call from VB.
I have also not found in the PL/SQL documentation how
a stored procedure is called once it is created.
Your help will be appreciated, as always.
