Varchar & Varchar2 in Stored procedure

I have created this stored procedure in Oracle:

CREATE OR REPLACE PROCEDURE get_product_code(prod_number IN VARCHAR) IS
CURSOR Get_code IS
For Get_code_cur IN Get_code LOOP

However, when i use SQL*Plus to view my stored procedure (command-->desc get_product_code'), i encountered the following:

Argument Name Type In/Out Default?
-------------------------- ------------------ ------ --------

I am curious why the type of the input parameter has been changed from VARCHAR to VARCHAR2?

As of Oracle 8, VARCHAR and VARCHAR2 are the same. However Oracle recommends using VARCHAR2 because VARCHAR may change in the future.

I'm not sure why it is changing it automatically for you though.
