PI84154: After PI79257, IGZ0272S CUNLCNV return code 12 reason code 3 may be seen from use of FUNCTION NATIONAL- 17/07/07 PTF PECHANGE

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• PI79257 in the April 2017 run-time PTF made performance
  improvements in the FUNCTION NATIONAL-OF() and FUNCTION
  DISPLAY-OF() use of the Unicode Conversion Services routine
  CUNLCNV that in some cases left the conversion technique
  parameter as binary zeros, causing those FUNCTIONs to fail:
  
      IGZ0272S Data conversion from CCSID {ccsid} to {ccsid} was
          unsuccessful. The return code from the Unicode
          Conversion Service CUNLCNV was 12 and the reason code
          was 3.
  
  The parameter error exposes a problem in conversion services
  whose symptom is bad conversion entries being displayed by the
  /d uni,all console command.
  

Local fix

• Back out the April PTF

  ****************************************************************
  The runtime routine that calls Unicode Conversion Service
  CUNLCNV has an error that left the 'Technique' field of the
  parameters to CUNLCNV service as binary zeros which cause
  CUNLCNV to misbehave. The field should be set to 'spaces'.
  
  FIXCAT keyword:  COB0501T/K   COB0502T/K   COB0601T/K
  

Problem conclusion

• The runtime routine has been corrected to set the 'Technique'
  field to 'spaces'.
