VMS Help DISCONNECT, Examples  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    1.$ DISCONNECT

      This command disconnects a physical terminal from a virtual
      terminal, but does not log the process out. Now you can use the
      physical terminal to log in again.

    2.$ RUN PAYROLL
 <Ctrl/Y>

      $ DISCONNECT/CONTINUE

      In this example, the RUN command is entered from a physical
      terminal that is connected to a virtual terminal. After the
      image PAYROLL.EXE is interrupted, the DISCONNECT command
      disconnects the physical and the virtual terminals without
      logging out the process. The /CONTINUE qualifier allows the
      image PAYROLL.EXE to continue to execute until the process
      needs terminal input or attempts to write to the terminal. At
      that point, the process waits until the physical terminal is
      reconnected to the virtual terminal; however, you can use the
      physical terminal to log in again and perform other work.
