pl/pgsql how to return multiple values from a function

Hi, all

I use "RETURNS RECORD" to return a multiple values from a function as
following but it doesn't work at all. Or is there any other way to do it?
Thank you jin advance!

CREATE OR REPLACE FUNCTION tesP_returnRec2( ) RETURNS INTEGER AS'
DECLARE
rec RECORD;
BEGIN
SELECT INTO rec tesP_returnRec1();
RAISE NOTICE ''jj=%, ss=%'', rec.jj,rec.ss;
RETURN 0;
END;'
LANGUAGE 'PLPGSQL';

CREATE OR REPLACE FUNCTION tesP_returnRec1( ) RETURNS RECORD AS'
DECLARE
rec RECORD;
BEGIN
SELECT INTO rec
CAST(100 AS INTEGER) AS jj,
CAST(''ABC'' AS VARCHAR(10)) AS ss;
RETURN rec;
END;'
LANGUAGE 'PLPGSQL';
