  When change accumulation is used as input to DRF, there is a
  situation where some CA records are not applied correctly.
  This situation occurs when an image copy is completely
  restored, however the CA contains update records that will be
  used to extend the database beyond what was restored from the
  image copy.  These CA update records also contain more than one
  change elements.
  

Problem conclusion

•  AIDS: RIDS/UTIL RIDS/DBS DBS/UTIL
    DEP: NONE
    GEN:
  
  *** END IMS KEYWORDS ***
  FRXIICA is fixed to correct a logic error which attempts to
  copy a CA update record into a database block after the IC is
  completely restored.  This error failed to determine if there
  are multiple change elements recorded with the CA record and
  failed to expand the record if it is compressed.  This fix
  addresses these issues.
  
  FRXIOCN0 is changed to initialize a new database block with
  zeros.
  
  FRXIOSM0, FRXIVCN0, and FRXIVSM0 are recompiled to pick up
  changes from FRXIICA.
  
  FRXPDSS0 is changed to correct a error in the log record count
  for reporting.
  
  FRXRBUF0 is changed to include change accumulation type '53'x
  records in the record count.
  
  FRXSDR00 was changed to add RECFM=FBA to the Report DCB.  The
  'A' specifies ANSI carriage control characters.  The CC
  characters were being printed as part of the output line
  instead of being taken as carriage control characters.
