SQL & PL/SQL :: Use REF Cursor In Query

I have a function :

FUNCTION WP19DUMMY(vname IN VARCHAR2) RETURN SYS_REFCURSOR
IS
tmpcur SYS_REFCURSOR ;
BEGIN
OPEN tmpcur FOR SELECT IVALUE FROM GENPARAMS WHERE NAME = vname;
RETURN tmpcur;
END WP19DUMMY;

I want to use the returned REF CURSOR in a SQL query. So I ran the following @ SQL prompt :

SELECT WP19DUMMY('TD') FROM DUAL;

and I am gettng the following result :

WP19DUMMY('TD
--------------------
CURSOR STATEMENT : 1
CURSOR STATEMENT : 1

IVALUE
-------------
0

BUT I do not want such a result. I want a result that will only return the IVALUE.
