  ****************************************************************
  When debugging a program using CEDF in dual-screen mode with
  security on, and the task being debugged has been purged,
  CEDF ABENDs AKEA 0C4 due to an AEY7 ABEND not being handled
  correctly by DFHEDFD.  The AEY7 is caused by DFHEDFP not
  performing the necessary security checks to ensure that CEDF
  is authorised to debug the specified transaction.
  

Problem conclusion

• DFHEDFP has been changed to always perform the necessary
  security checks to confirm that CEDF is authorised to debug the
  transaction under its control.
