SQL & PL/SQL :: Procedure Calling Methods

I have created this procedure for printing ename,sal,job as output using empno as input:-

CREATE OR REPLACE PROCEDURE p_get (
p_empno NUMBER,
p_name OUT VARCHAR2,
p_sal OUT NUMBER,
p_job OUT VARCHAR2
)
IS
BEGIN
SELECT ename, sal, job
INTO p_name, p_sal, p_job
FROM emp
WHERE empno = p_empno;
END;

Now My Requirement I want to call this procedure using Positional,Named and Mix Methods...I am calling this procedure using Positional Method:-

declare
p_name varchar2(20);
p_sal number;
p_job varchar2(20);
begin
p_get(7369,p_name,p_sal,p_job);
dbms_output.put_line('Name='||p_name||' Salary='||p_sal||' Job='||p_job);
end;
