APAR status

Error description

• A COBOL program is not reading every records with "GRC" value in
  WS-GRC zone.
  
  ===== ACTUAL OUTPUT:
  $ export E01=FICLU
  $ ./LECFIC
  PAS DE GRC :     ENREGISTREMENT : 000063445 DEBUT ENREG >
  < FIN ENREG
  $
  
  
  ===== EXPECTED OUTPUT:
  Records 63445 and 63446 should be read properly
  

Local fix

• N/A
  

Problem summary

• USERS AFFECTED:
  COBOL users with Line Sequential files in DOS format (\r\n
  instead of just \n) are affected by this issue.
  
  PROBLEM DESCRIPTION:
  The end of a record could be missed and subsequent records could
  be read improperly.
  
  It is possible that the \r\n are split amongst two buffers, and
  if that happens, we did not treat them as a proper record
  delimiter.
  

Problem conclusion

• When a buffer ends with \r, we now check the next buffer for \n.
  

Temporary fix
