% some "nice" prolog settings...  see assignment 8's
% description for the details on what these do
% -- but it's not crucial to know the details of these Prolog internals
:- set_prolog_flag( prompt_alternatives_on, groundness ).
:- set_prolog_flag(toplevel_print_options, [quoted(true), 
     portray(true), attributes(portray), max_depth(999), priority(699)]).


% to run your parse-checker
%   make sure you have the grammar files
%       g0.pl
%       g1.pl
%       g2.pl
%       g3.pl
%   in your directory with parse.pl
%
%   Then run
%
% :-  [part4].
% :-  [g0].   % or whatever grammar you'd like to check
%
% :-  parse([s], [1, +]).
% 
% No
%
% :- parse([s], [1, +, 0, +, 1]).
%
% Yes

% don't let parse get too big!
% you'll need relatively few lines of code here:
