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

        CMS> COPY CLASS INIT_CLASS INITX_CLASS "experimental version"
        %CMS-S-COPIED, class DISKX:[PROJECT.CMSLIB]INIT_CLASS copied
        to INITX_CLASS

      This command creates a new class named INITX_CLASS in the same
      library as the old class.
