/sys$common/syshlp/helplib.hlb CREATE, Parameter  *Conan The Librarian (sorry for the slow response - running on an old VAX)

 filespec[,...]

    Specifies the name of one or more input files to be created.
    Wildcard characters are not allowed. If you omit either the file
    name or the file type, the CREATE command does not supply any
    defaults. The file name or file type is null. If the specified
    file already exists, a new version is created.
