  ****************************************************************
  When ARSCSVFL is constructing the query SQL, and the field is
  decimal with a precision of 0, the X'00' that indicates the end
  of the string will be overlaid.  This causes subsequent string
  operations to continue looking in storage until it finds a
  X'00'. The result of this is a malformed query string leading to
  the ARS2041E message.  The malformed query string can also cause
  the OD server to crash, or possibly cause heap corruption in WAS
  if the subsequent string operations overflow the heap element.
  

Problem conclusion

• ARSCSVFL is changed to not overlay the X'00'.
  
  This APAR resolves the problem in the z/OS code, in particular
  the z/OS ODWEK servlet.  If the ARS0241E is observed as a result
  of using the Windows client on a folder with a decimal field
  with a precision of zero, the 8.5.0.2 version of the Windows
  client contains the fix and should be installed to resolve the
  problem in the Windows client.
