APAR status

• Closed as program error.

Error description

• The following abend occurred while using CEDX
  
  DFHAP0001 .. An abend (code 0C2/AKEX) has occurred at
               offset X'FFFFFFFF' in module DFHEDFX.
                                                                 .
  This was an abend0c2 in DFHLIRET at offset x'154'.
  At the time of the abend, DFHLIRET expected a CSA address in
  register 13, but this was zeroes.
  A CSA address is obtained by following the current TCB to its
  AFCB block, where at +8 can be the CSA address.
    This is true following a QR TCB to its AFCB, however the
  processing here was under an SO TCB.
  Following an SO TCB to its AFCB block, this correctly does not
  contain a CSA address, and lead to the abend0c2,
  privileged operation exception.
    It looks like a switch to the QR TCB needs to occur for this
  case.
                                                                 .

  ****************************************************************
  An attempt to debug a CICS TCPIPSERVICE OPTIONSPGM with the
  CEDX debugger fails with an 0C2 program check in DFHLIRET
  because DFHEDFX is called on the SO TCB.

Problem conclusion

• CICS has been changed to switch from the SO TCB
  to the original TCB before linking to the Options Program.
