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

  $ SET HOST/DUP/SERVER=MSCP$DUP/TASK=DIRECT R2DH5Y
  %HSCPAD-I-LOCPROGEXE, Local program executing -
 type ^\ to exit utility

      The SET HOST/DUP command in this example connects the user
      terminal to the utility program called DIRECT executing on a
      storage controller named R2DH5Y under direction of the MSCP$DUP
      server.
