Client Tools :: Execute A Procedure With Parameter Of Object Type?

I am trying to execute the procedure from toad, where the type is like an object.How can I do that?

CREATE OR REPLACE TYPE list_t AS TABLE OF list_objtype;
CREATE OR REPLACE TYPE list_objtype AS OBJECT
( Emp_ID NUMBER(5),
EMp_Name VARCHAR2(32 BYTE)
);

In the following procedure I am calling list_t, but how would i pass the values to it?

PROCEDURE modify_settings
( p_List in list_t,
p_info out varchar2)
DECLARE
p_List TABLE;

[code]...
