Normally if a user being watched tries to type when he does not have
   keyboard control, Peek/Spy will ring his terminal bell to inform
   him that the watcher currently has control of his keyboard.

   /NOBEEP keeps this warning bell from ringing on the terminal being
   watched.

   A default value can be specified in the logical WATCHER$NOBEEP.

   With NOBEEP, when the user being watched does not have keyboard
   control, his keyboard will just appear to "go dead" instead of
   beeping when he tries to type.
