       /WIDTH=(keyword[,...])

    Formats the width of the display. If you specify only one
    keyword, you can omit the parentheses. Possible keywords are
    as follows:

    DISPLAY=n  Specifies the total width of the display as an integer
               in the range 1 to 256 and defaults to zero (setting
               the display width to the terminal width). If the total
               width of the display exceeds the terminal width, the
               information will be truncated.

    FILENAME=n Specifies the width of the file name field; defaults
               to 19 characters. If you request another piece of
               information to be displayed along with the file name
               in each column, file names that exceed the n parameter
               cause the line to wrap after the file name field. (See
               the /COLUMNS qualifier.)

    OWNER=n    Specifies the width of the owner field; defaults to
               20 characters. If the owner's user identification
               code (UIC) exceeds the length of the owner field, the
               information will be truncated.

    SIZE=n     Specifies the width of the size field; defaults to 6
               characters on systems prior to OpenVMS Version 6.0; the
               default is 7 characters on OpenVMS Version 6.0 systems
               or higher. If the file size exceeds the length of the
               size field, the field is filled with asterisks.
