Oracle -- Multiple SELECT statement ?

The below SELECT displays the EMPLOYEE's MANAGER.

  SELECT SUP_POS_CODE FROM COMPANY_POSITION
  where POS_CODE = '101/3802'

What SELECT or PL/SQL will allow me to
enter '101/3802' and get the below, indented ?

    100/1000 PRESIDENT
      101/3005 MANAGER
       101/3802 EMPLOYEE
        ........ there will be more layers
                 depending on who is picked
