      This example shows how to spawn a subprocess (MAGNANI_1) to
      invoke Mail and use the ATTACH command to move between Mail
      (MAGNANI_1) and a DECTPU editing session (MAGNANI). The ATTACH
      command allows you to transfer control between subprocesses.

                                   NOTE

       Always enter the SPAWN command to create a new process and
       the ATTACH command to connect to a process that already
       exists. For more information on the SPAWN and ATTACH
       commands, exit from Mail and enter HELP SPAWN or HELP ATTACH
       at the DCL prompt.
