Command: exit
  EXIT exits the current FreeDOS Command Shell.
Syntax:
  EXIT [/?]
Options:
  /?  Shows the help.
Comments:
  Terminates the currently running shell, unless FreeCOM had been started
  with the /P option. In this case, EXIT works like CANCEL (a hidden
  command).
Examples:
  command.com (works without option /P)
  exit        (terminates the currently running shell)
  exit /?     (Shows the help)
