Qualifiers

/LISTING 
  /LISTING[=file-spec]

  Determines whether a sequence-numbered listing file, showing the
  original and inserted lines and an audit trail, is produced during
  the editing process. If you do not include a file specification, 
  the listing file takes the same name as the input file, with a file
  type of LIS. By default, no listing file is produced.

/OUTPUT
  /OUTPUT[=file-spec]

  Specifies the output file to be used in the editing session.  If you
  do not include a file specification, the output file has the same
  name and type as the input file, with a version number one higher
  than the highest existing version.

/HEADER
  /HEADER/OUTPUT=file-spec

  Determines whether the output file is created as a VFC format
  sequential file with the line insert number and audit trail
  information in the record header block (RHB) for the records.

/UPDATE
  /UPDATE[=(update-file-spec[,...])]
           
  Indicates the file or files containing the editing commands and
  changes to be applied to the input source file.   The default file
  type of these files is UPD.
