Display a register in a function

Question

Hi,
I have a PL/SQL function compiled succesfully, but it doesn't works as I wish, and I don't know why. So I tried to display a register of a table but there are errors. Here is the code:
create or replace
PACKAGE BODY "SML_ACUMULADOS" as
-- Para que el usuario actualice los stocks erróneos de una clave desde Discoverer
FUNCTION actualizar_acumulados(p_counipro in VARCHAR2,
p_cjclmapr in VARCHAR2,
p_nuprovee in VARCHAR2,
p_caextrap in NUMBER,
p_caextran in NUMBER,
p_caexexpl in NUMBER,
p_caexalma in NUMBER)
RETURN NUMBER
IS
CURSOR c_acumulados is
SELECT counipro,
cjclmapr,
nuprovee,
caextrap,
caextran,
caexexpl,
caexalma
FROM sml_movimientos_2009
WHERE COUNIPRO = p_counipro
AND CJCLMAPR = p_cjclmapr
AND NUPROVEE = p_nuprovee;
--SET VERYFY OFF
SET SERVEROUTPUT ON SIZE 20000; --error
BEGIN
OPEN c_acumulados;
FOR i in c_acumulados LOOP
IF p_caexalma IS NOT NULL AND p_caexalma != i.caexalma THEN
UPDATE sml_movimientos_2009
SET CAEXALMA = p_caexalma
WHERE COUNIPRO = p_counipro
AND CJCLMAPR = p_cjclmapr
AND NUPROVEE = p_nuprovee;
DBMS_OUTPUT_LINE(i.caexalma); --Error
RETURN 1;
ELSE RETURN 0;
END IF;
END LOOP;
RETURN p_caexalma;
CLOSE c_acumulados;
END;
END;
The error I display is:
Error(29,21): PLS-00103: Encountered the symbol "ON" when expecting one of the following: := . ( @ % ; not null range default character The symbol "; was inserted before "ON" to continue.
How can I display the caexalma value?
Thanks.

Although what you told me works, the problem it's not fixed. Because I'm trying to display the value inside the table, that is, i_caexalma, not the parameter I type in the function. That's why I typed in the code:
DBMS_OUTPUT_LINE(i.caexalma); --Error
The important code is:
IF p_caexalma IS NOT NULL AND p_caexalma != i.caexalma THEN
UPDATE sml_movimientos_2009
SET CAEXALMA = p_caexalma
WHERE COUNIPRO = p_counipro
AND CJCLMAPR = p_cjclmapr
AND NUPROVEE = p_nuprovee;
--DBMS_OUTPUT_LINE(i.caexalma);
RETURN c_acumulados.i_caexalma;
p_caexalma is the parameter of the function and it's possible to display it. But is it possible to display i.caexalma value? I want to check if this conditional is OK and the table sml_movimientos is updated. Now I know that this table is not updated and I want to know why.
Thanks.
