VMS Help EXCHANGE, DIRECTORY, Description  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    The output of the DIRECTORY command depends on the volume format
    and on certain formatting qualifiers and defaults. The following
    are the formatting qualifiers:

    /ALL       /BLOCKS     /BRIEF     /COLUMNS    /DATE
    /FULL      /OCTAL      /OWNER     /SIZE

    The files that are listed always appear in the order in which
    they appear in the volume directory or the order in which they
    reside on a magnetic tape.
