PBD question

I can't seem to regain control after the while loop... Any ideas?
It just hangs there, and displaying the correct data

import java.math.*;
import com.pbd.pub.jdb400.*;

public class Item
{

  public static void main(String argv[]) {
 
    String ItemNumber = argv[0];
       
    Jdb400.setAS400("xxx.xxx.xx.xx "me", "meagain");
    Jdb400KeyedFile PODETAIL = new Jdb400KeyedFile("LIB1/PMLPDQS1");

    PODETAIL.SETLL(ItemNumber);

     while (PODETAIL.READE(ItemNumber))
        System.out.println(PODETAIL.getField("PDPOID"));

///*** the pogram just stops right here, (* it did display the coorect data   *) Then I tried the   PODETAIL.CLOSE();  that didn't work, so then I add the following lines of code, to see if it would look at some other data again, and that didn't work...  ****/

    PODETAIL.SETLL("ED-265-P");

     while (PODETAIL.READE("ED-265-P"))
        System.out.println(PODETAIL.getField("PDPOID"));

    System.exit(0);
  }
       
}
