How to call package function and procedure by PL/SQL

Question

Dear all,
I created a package and I want test it by a select statement. e.g. select packagename.function(1, 'A') . However, there is an error message. "ORA-14551: cannot perform a DML operation inside a query ".
In the package, there is a function and I passed two parameters to the function and return a number. These two parameters will be used in the cursor select statment. Is there sth wrong that I use the cursor with the parameters? What can I do then?
On the other hand, I want to test the package procedure by using select statement in SQL Plus. How can I call it (with parameter)?
Remark: I am using Oracle 8i.
Thanks for advance!!

SQL> create or replace package body pack_test
