PM81114: SEQUENTIAL TERMINAL DATA UNEXPECTEDLY UPPER CASE TRANSLATED

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Customers sequential terminals are defined appropriately to
  support mixed case input data.  All sequential terminals appear
  to work correcty with lower case transaction ids as input except
  for one particular sequential terminal. This one sequential
  terminal causes upper case translation to incorrectly occur,
  resulting in message DFHAC2001 to be produced. The DFHAC2001
  message cleary shows the tranid as upper case. The message is
  correctly produced as the tranid does not exist as upper case.
  The data within the input dataset is correct and has proven to
  work with all other sequential terminals. Customer also tried
  changing the sequence of order of the definition defining the
  sequential terminal within the DFHTCT and the problem continues
  to follow the specific terminal.
    The problem arises at label TCTINTD1 within DFHTCP. A TRT
  (translate and test) instruction causes register 2 to be changed
  then later register 2 is used as a pointer to the TCTTE, causing
  bad decisions to then be made based on random data being pointed
  to.

  ****************************************************************
  A sequential terminal transaction id is incorrectly translated
  to upper case because the TCTTE base register address was
  corrupted whilst being processed.
  

Problem conclusion

• DFHTCTI (DFHTCP) has been changed so that the TCTTE base
  register is not corrupted.
