  ISTTRCLT is used by many VTAM components to add, find, and
  remove elements from a specified list. When the ?LSTREM macro
  is used to remove a specific element (with the ELEMENT keyword)
  from a sequential or keyed sequential list, and the element is
  not found on that list, ISTTRCLT abends.
  

Problem conclusion

• Module ISTTRCLT and macro LSTREM have been changed to allow
  a caller to request that a FFST probe (ISTTRCZ2) be taken
  when a ?LSTREM is issued for a specific element to be removed
  from a sequential or keyed sequential list and the element is
  not on that list.
  The additional modules included in this APAR have had the FFST
  keyword added to the appropriate ?LSTREM macros that they issue.
  
  VTAM Diagnosis (LY43-0078-00), Appendix B (First Failure Support
  Technology (FFST) Probes), FFST Probe Descriptions for Topology
  and Routing Services Probes (Table 50) has been changed to add
  the following probe description:
    Probe name   Module     Description                  Dump Type
    ISTTRCZ2     ISTTRCLT   A ?LSTREM ELEMENT() macro    Full
                            has been issued to remove
                            an element from a sequential
                            or keyed sequential list,
                            but the element is not on
                            the list.
