The EXTRACT command displays one or more repository elements in
    the specified format. You can choose the DEFINE command format
    or the ANSI-standard syntax for the C programming language. By
    displaying an element in the DEFINE command format, the EXTRACT
    command makes it easier for you to create new versions of an
    uncontrolled element. By displaying an element in the ANSI C
    programming language format, you can use the definition when
    building applications.

    You can capture the output of the EXTRACT command in a file by
    issuing the SET OUTPUT command as the preceding command. For
    the DEFINE command, edit and execute the command file with the
    @ command. For the ANSI C programming language format, edit the
    output file to remove the EXTRACT command and then include the
    file in an application.

    If a field has character set attributes, you can display them
    using the SHOW and EXTRACT commands; in addition, you can use
    the SHOW command to display size information of a field in both
    character-based size and octet-based size. See the description
    of SET CHARACTER_SET command and the DATATYPE_Field_Property help
    topic found under the fld-properties topic for more information.
