How to specify more than Two Tables in NATURAL JOIN

Question

Hi,
I am using Oracle9i R-2. I want help in writing a Query using Two Tables in SQL*PLUS. I am using ANSI/ISO Standrard for table-joins:
select col1, col2, descr
from tab1 natural join tab2
There are two columns col1 & col2 is common between thse two tables. So, it will join them and query execute well.
How can i use 3rd table tab3 in the same way in Natural Join...? If column col1 & col2 is available in tab3 also.
I tried this way, but it gives me error:
select col1, col2
from tab1 natural join tab2 natural join tab3
Is it possible to specify more than two tables in Natural Join Clause.
Please check that out & help please. Thanks.
Regards,

I do not get an error when I try the same thing on the same version, as demonstrated below. Can you post your table structure and a copy and paste of a run of your actual query with the error that you are receiving?
