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

  $ LIBRARY/REMOVE=(LIB_EXTRCT_MODS,LIB_INPUT_MAC)/LOG LIBRAR

      This LIBRARY command requests the removal of the global symbols
      LIB_EXTRCT_MODS and LIB_INPUT_MAC from the object library
      LIBRAR.OLB. The /LOG qualifier requests that the removal of
      the symbols be confirmed by messages.
