VMS Help CMS, CREATE, LIBRARY, Command Parameters  *Conan The Librarian (sorry for the slow response - running on an old VAX)

 directory-specification

    Specifies one or more valid VMS directories. Each directory must
    not contain any files. A directory that is to be used as a CMS
    library cannot be your current default directory. If you specify
    more than one VMS directory, you must separate the directory
    specifications with commas. Wildcards are not allowed.

 remark

    Specifies a character string for the creation remark of the new
    library to be logged in the history file with this command. The
    remark is enclosed in quotation marks. If no remark was entered, a
    null remark ("") is logged in the history file.
