  occurred at offset X'23E2' in module DFHDSAT.  The program check
  abend0C4 is a PIC10 segment translation exception.  The failing
  instruction is a CLC ( D507 A008 32CC ) with R10 containing
  ebcidic.  R10 was loaded from R12 ( 58A0 C068 ) attmepting to

  ****************************************************************
  When CICS performs a warm or emergency restart it calls DFHW2RP
  to restore resource definitions from the CATALOG in routine
  RECOVER_DEFINITIONS. DFHW2RP makes a CHANGE_MODE call onto
  the QR TCB. Its initial TCB_TOKEN is not saved and on the way
  out of RECOVER_DEFINITIONS it attempts to return to an initial
  TCB_TOKEN that has not been set and most likely points to an
  invalid TCB_TOKEN or unreadable storage, resulting in CICS
  reporting either the INVALID_TCB_TOKEN or an 0C4 ABEND.

Problem conclusion

• DFHW2RP recover_definitions routine has been changed so that it
  stores the initial TCB_TOKEN. This allows the CHANGE_MODE on
  exit to work correctly.
