Comments

• DFHEBF has been changed to replace the DFHIC WAIT with a
  threadsafe dispatcher wait. In addition, BIF DEEDIT and BIF
  DIGEST commands are now marked as being threadsafe in DFHEIP.
  The CICS Transaction Server for z/OS Application Programming
  Reference Version 4 Release 1 manual SC34-7159-02 will be
  changed to add the following commands to the list of
  threadsafe commands in the section "CICS threadsafe commands
  in the API" on page 17:-
  BIF DEEDIT
  BIF DIGEST
  DEFINE COUNTER and DEFINE DCOUNTER
  DELETE COUNTER and DELETE DCOUNTER
  GET COUNTER and GET DCOUNTER
  REWIND COUNTER and REWIND DCOUNTER
  UPDATE COUNTER and UPDATE DCOUNTER
  Similar changes will be made to "Existing API commands made
  threadsafe in this release" in the What's New manual
  GC34-7192-02 on page 105 and to "API commands that were made
  threadsafe" in the Upgrading from CICS TS Version 2.3" (and 3.1
  and 3.2 versions) manuals GC34-6996-03, GC34-6997-03 and
  GC34-6998-03 on page 15.
