Peek/Spy accepts nodenames in the targets of its PEEK, SPY, WATCH
   and SHOW USERS commands.

   Use a standard VMS DECnet node specification ending with a double colon.
   This may contain an accesss control string per standard VMS DECnet rules.

   Peek/Spy must be running on the target node, and the PEEK and SPY
   objects/applications must be defined for DECnet on the target nodes.
   See the PEEK Node_Names Subtopic: Set-up.

   Examples:

   $ PEEK NODEA::J_DOE                     ! Watch process J_DOE on NODEA.
   $ SPY NODEA"SYSTEM SYSPASS"::J_DOE      ! SPY via SYSTEM account on NODEA.
   $ SPY/TERM=(NODEA::LTA*,NODEB::LTA*)    ! Watch LTAs on NODEA and NODEB.
   $ PEEK/SHOW USERS NODEA::J_DOE,P_SMITH  ! Show these two users on NODEA.

   Standard VMS * and % wildcards are allowed in the nodename portion of
   a target specification (providing PEEK has been configured for use of
   wildcards in nodenames). See the PEEK Node_Names Subtopic: Wildcards.
