      MAIL>
      This example shows how to use the SPAWN command to create a
      subprocess in which you SET HOST to another node. When you want
      to leave node MARS and move back to node BETA, enter the DCL
      command LOGOUT. The /NOLOGICAL_NAMES qualifier prevents the
      logical names of the parent process from being copied to the
      subprocess.
