VMS Help DECnet-Plus, DCL Commands, APPEND, Wildcards  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    Wildcards provide a method for generalizing a file designation to
    encompass a set of local files. Standard DCL wildcard techniques
    work for both local (RMS) files and remote files for those remote
    FTAM systems that support the NBS-9 document type. If using
    wildcard techniques with remote FTAM systems does not work, you
    should complete the file designation.

    The supported wildcard characters include an asterisk (*) to
    represent a text string, a percent sign (%) to represent a single
    character, or empty brackets ([ ]) to represent all files in the
    local default RMS directory.
