Problem summary

• ****************************************************************
  * USERS AFFECTED: All CICS Users.                              *
  ****************************************************************
  * PROBLEM DESCRIPTION: Misleading trace interpretation.        *
  ****************************************************************
  Looking at a CICS trace when an EXEC CICS INQUIRE MVSTCB has
  been issued may show something like the following:
  KE 0503 KEDS  EXIT  - FUNCTION(INQUIRE_MVSTCB)
  RESPONSE(EXCEPTION) REASON(NOT_FOUND) TCB_ID(CICS.)
  TCA_TASK_NUMBER(2B2870)
  .
  The TCB_ID and TCA_TASK_NUMBER are residual data and should not
  be specified.
  

Problem conclusion

• DFHKEDS INQUIRE_MVSTCB has been changed to set TCB_ID to NONE
  and TCA_TASK_NUMBER to 00000 when it returns an exception
  response of not found.
