Put SQL query in a function/ call function from region

Question

How can I write a SQL query (like SELECT EMPNO, ENAME, JOB FROM EMP) as PL/SQL function, and then call this function from the PL/SQL Function Returning SQL Statement region?
Thanks, Tom

thanks jverd for your quick reply.
I know passing in a reference to an object will do the job if I want to change the value several parameters in one function call.
But I want to ask, is there any other ways?
the following code works.....
public class TestParameter {
     public static void main(String[] args) {
          Test2 t2 = new Test2();
          invokeChange(t2);
          System.out.println("x = " + t2.x + "\t y = " + t2.y);
     static void invokeChange(Test2 t2) {
          t2.x = 10;
          t2.y = 15;          
class Test2 {     
     int x;
     int y;     
}
