1    /ALL

       /ALL
       /NOALL

    Lists all deleted or unused files on an RT-11 volume, in addition
    to other files selected by the command. For example, the
    following command lists all MACRO source files, in addition to
    deleted and unused files:

    EXCHANGE> DIRECTORY DMA0:*.MAC/ALL

2    /BADBLOCKS

       /BADBLOCKS
       /NOBADBLOCKS

    Scans the volume to find any blocks that return read errors. The
    data on the volume is not modified. If a bad block replacement
    table is present, the contents of the table are displayed. This
    is valid for RT-11 volumes only.

3    /BLOCKS

       /BLOCKS
       /NOBLOCKS

    Lists the starting block number of the file. This qualifier is
    valid only for directories of RT-11 devices. The first block of
    the device is block number 0. The default is /NOBLOCKS.

4    /BRIEF

       /BRIEF
       /NOBRIEF

    Includes only the file name of each file to be listed. Specifying
    the /BRIEF qualifier is equivalent to specifying /NODATE/NOSIZE.
    The default is /BRIEF.

5    /COLUMNS

       /COLUMNS=n

    Lists the files, using the specified number of columns on each
    line of the display. This qualifier is used in conjunction with
    the /BRIEF qualifier (either explicitly or by default). The
    default number of columns is dependent on the volume format and
    the information requested. The DIRECTORY command attempts to use
    as many columns as possible. If you request too many columns,
    DIRECTORY displays a message and reduces the number of columns to
    the number that fit on the listing.

6    /DATE

       /DATE
       /NODATE

    Includes the date for each file listed. If you omit this
    qualifier, the default is /DATE.

7    /DELETED

       /DELETED
       /NODELETED

    Lists a directory of files that have been deleted from an RT-11
    device, but whose file name information has not been destroyed.
    The listing includes the file names, types, sizes, creation
    dates, and starting block numbers (in decimal, unless you also
    specify the /OCTAL qualifier) of the deleted files. The /DELETED
    qualifier is valid only with block-addressable volumes in RT-11
    format. The default is /NODELETED.

8    /FREE

       /FREE
       /NOFREE

    Includes unused areas in the directory listing. The /FREE
    qualifier is valid only with RT-11 formatted volumes.

9    /FULL

    Lists all the available information for each file. The format
    of the listing depends on the format of the volume. The /FULL
    qualifier overrides the default brief listing format.

10    /OCTAL

       /OCTAL
       /NOOCTAL

    Controls whether numeric information is displayed in decimal or
    octal format. The default is /NOOCTAL; numbers are displayed in
    decimal radix. Dates are always displayed in decimal format.

11    /OUTPUT

       /OUTPUT[=file-spec]

    Writes the DIRECTORY output to a specified file, rather than
    to the current SYS$OUTPUT device. If you specify the /OUTPUT
    qualifier without a file specification, the output is directed to
    SYS$OUTPUT. If you omit the file type in the file specification,
    the default file type is .LIS. If you specify a file type
    and omit the file name, the default file name is EXCHDIRE. No
    wildcard characters are allowed in the file specification.

12    /OWNER

    Displays information about the owner of a volume and the files on
    the volume. For RT-11, the volume owner is shown. For DOS-11, the
    UIC of the file owner is shown.

13    /PRINTER

    Queues the command output for printing under the name specified
    by the /OUTPUT qualifier. If you specify /PRINTER without
    the /OUTPUT qualifier, the output is directed to a file named
    EXCHDIRE.LIS, which is spooled for printing and then deleted.

14    /SIZE

       /SIZE
       /NOSIZE

    Displays the file size in blocks for each file listed. The
    default is /SIZE.

15    /SUMMARY

       /SUMMARY
       /NOSUMMARY

    Lists a summary of the usage of the directory segments for an
    RT-11 volume. If a bad block replacement table is present, the
    contents of the table are displayed.

16    /VOLUME_FORMAT

       /VOLUME_FORMAT=option

    Defines the physical format of the volume to be processed. The
    default format is dependent on the device type.

    The EXCHANGE command DIRECTORY is not valid for Files-11 devices.
