I would appreciate if someone could help

I need to pass IN OUT record variables (Type Record) to a procedure
using DBMS_SQL.

create or replace function func1 (p_emprec IN OUT EMP%rowtype,
p_return_cd OUT number, p_return_msg OUT varchar2) return boolean
as
begin
...
-- assign values to emprec record, to return_cd and return_msg
return (true)
exception
return false;
end;


The calling pl/sql block is somewhat like this.
....
-- the statement to be called
v_stmt := 'begin ' ||
':i_v_result := '||v_func||
'(:i_v_emprec,'||
' :i_v_return_cd, :i_v__return_msg); '||
' end;';

v_cur_id := DBMS_SQL.OPEN_CURSOR;
DBMS_SQL.PARSE(v_cur_id,v_stmt,DBMS_SQL.NATIVE);
-- bind the variables for v_func() call
DBMS_SQL.BIND_VARIABLE(v_cur_id,':i_v_result',v_re sult);
DBMS_SQL.BIND_VARIABLE(v_cur_id,':i_v_emprec',v_em prec);
DBMS_SQL.BIND_VARIABLE(v_cur_id,':i_v_return_cd',v _return_cd);
DBMS_SQL.BIND_VARIABLE(v_cur_id,':i_v_return_msg', v_return_msg);
v_dyn_result := DBMS_SQL.EXECUTE (v_cur_id);
-- get the OUT variables from v_func() call
DBMS_SQL.VARIABLE_VALUE(v_cur_id,':i_v_result',v_r esult);
DBMS_SQL.VARIABLE_VALUE(v_cur_id,':i_v_emprec',v_e mprec);
DBMS_SQL.VARIABLE_VALUE(v_cur_id,':i_v_return_cd', v_return_cd);
DBMS_SQL.VARIABLE_VALUE(v_cur_id,':i_v_return_msg' ,v_return_msg);
DBMS_SQL.CLOSE_CURSOR(v_cur_id);
....


When I compile, I get the following error msgs
PLS-00306: wrong number or types of arguments in call to 'BIND_VARIABLE'
PLS-00306: wrong number or types of arguments in call to 'BIND_VARIABLE'
for first two bind_variables() calls and

PLS-00306: wrong number or types of arguments in call to 'VARIABLE_VALUE
PLS-00306: wrong number or types of arguments in call to 'VARIABLE_VALUE
for first two variables_value() calls

Any workaround for this. Thanks a lot.
