Command_Qualifiers

      /CHECK_SEQUENCE
      Verifies the sequence of the records only in Merge input
      files. By default Merge checks the sequence of the records.
      Use only with the MERGE command.

      /COLLATING_SEQUENCE
      Selects one of three predefined collating sequences for
      character key fields, or specifies the name of a National
      character set (NCS) collating sequence to be used in comparing
      character keys. Sort arranges characters in ASCII sequence by
      default; the EBCDIC and Multinational sequences can also be
      used.

      High-performance Sort/Merge: The high-performance Sort/Merge
      utility currently supports all collating sequences except NCS.


      /DUPLICATES
      By default, Sort retains multiple records with duplicate keys.
      The /NODUPLICATES qualifier eliminates all but one of multiple
      records with duplicate keys.


      /KEY
      Describes key fields, including the position, size, sorting
      order, and data type.


      /PROCESS
      Defines the internal sorting process. The /PROCESS qualifier
      allows you to choose one of four processes: record, tag,
      address, or index. By default, SORT uses a record sorting
      process. Use only with the SORT command.

      High-performance Sort/Merge: The high-performance Sort/Merge
      utility currently supports only the record process.


      /SPECIFICATION
      Identifies a Sort or Merge specification file.

      High-performance Sort/Merge: The high-performance Sort/Merge
      utility does not currently support the use of specification
      files.


      /STABLE
      Directs records with equal keys to the output file in their
      input file order. The default condition is /NOSTABLE.


      /STATISTICS
      Displays a statistical summary that can be used for
      optimization.

      High-performance Sort/Merge: The high-performance Sort/Merge
      utility supports the display of some statistics, but not all
      of them. See the full description for information.


      /WORK_FILES
      Increases the number of Sort work files by any number from
      1 to 10 inclusively to make each work file smaller. If the
      available disks are too small or too full for work files,
      increasing the number of files can improve the efficiency of
      the sort operation. Use only with the SORT command.

      High-performance Sort/Merge: The high-performance Sort/Merge
      utility supports from 1 to 255 work files.
