SET NODEFAULT SECTION FILE    (default)
  Cancels the default section file for saving attributes and other
  customizations.
  Example:
     If you prefer to save in a command file instead of a section file, use
     the following commands, so that when you save attributes, EVE asks
     whether to save in a command file and shows the name of your default
     command file (TPU$COMMAND.TPU) in the prompt line:
        Command: SET NODEFAULT SECTION FILE
        Command: SET NOSECTION FILE PROMPTING
        Command: SET DEFAULT COMMAND FILE tpu$command.tpu
        Command: SAVE ATTRIBUTES
  Usage notes:
  o  This does not determine the section file executed at startup, but only
     the section file for saving your customizations. For information about
     specifying a section file at startup, see help on Section Files.
  o  The following table shows the effects of SET NODEFAULT SECTION FILE,
     depending on whether you enabled or disabled section file prompting for
     saving attributes:

     SET SECTION FILE PROMPTING      When you save attributes, EVE asks you
     (default)                       whether to save in a section file.  If
                                     you respond Yes, EVE asks for the name
                                     of the section file.
     SET NOSECTION FILE PROMPTING    When you save attributes, EVE asks
                                     whether to save in a command file---
                                     without prompting for a section file.
  o  These settings or effects apply when you use SAVE ATTRIBUTES or SAVE
     SYSTEM ATTRIBUTES, or when you save attributes as part of exiting or
     quitting.
  o  To save your setting for future editing sessions, use SAVE ATTRIBUTES
     to create a section file or to create or update a command file---see
     help on Attributes.
