The following are examples of the SPAWN command:

    1.$ DEFRAGMENT
      DFO> SPAWN
      $

      The SPAWN command creates a subprocess and transfers terminal
      control to the created subprocess.

    2.
      DFO> SPAWN SHOW DEFAULT
         DISK$1:[JONES]
      DFO>

      The SPAWN command creates a subprocess and executes the DCL
      command SHOW DEFAULT in the created subprocess. Control then
      returns to the Disk File Optimizer parent process.
