Error description

• An EXCI job using channels and containers failed with
  DFHEX0001  An abend (code ---/4039) has occurred in module
  DFHXFQ.
  An error occurred at program DFHXCPRX UI48954 offset +000E46.
  The Link Request has failed. Return codes are:
  00000088  00000623
  .
  The problem is in the transformer module DFHXFQ which includes
  DFHXFPC.MACRO which generates code which works in either the
  Batch (EXCI) or Online (CICS) Online environment.
  The transformer uses a DSECT which maps Batch and Online data
  areas. DFHXFQ, in Batch, is incorrectly picking up a field whch
  is only valid in the Online environment, and the mapping of
  data areas means that a pointer is being used incorrectly.

  CICS Transaction Server 5.4 provides Channel and Container
  support to EXCI applications.
  The CICS Transformer, working in the client (batch) environment,
  incorrectly uses a pointer which is only applicable in the
  server (online) environment.
  This can result in an 0C4 program check if the pointer contains
  the address of invalid storage, or can result in application
  data being corrupted (a fullword is incremented.) Unpredictable
  results may occur.

Problem conclusion

• DFHXFPC.MACRO has been changed to generate the correct code
  for the batch environment.
