gui matlab help

Hey, I'm messing around gui for a digital clock that I'm making in matlab and I'm stuck. I have drop down file with 'Exit' in it. I'm obviously trying to make it so when you select exit, the figure closes, but I can't figure it out. Any suggestions to get the exit button working?

heres what I have so far. The first block of code is the working one just so you can see what it looks like. To exit you have to use ctl+C. The second code block is what I think it should be, but doesn't work.

HFIG = figure('Name', 'Digital Clock', 'Numbertitle', 'off', 'Position', [400 300 350 100], ...
    'Menubar', 'none', 'Resize', 'on');
 filemenu = uimenu('Label', 'File');
uimenu(filemenu, 'Label', 'Exit', 'Callback', [mfilename, '(''EXIT'')']);

th = text(0.5,0.5,'xxx') ; % retrieve handle
set(gca,'visible','off') ;
set(th,'visible','on','horizontalalignment','center')
while(1),
  c1 = datestr(clock,13) ;
  set(th,'string',c1);% set the string
  pause(.1) ; % break with ctrl-C
  end  

and heres the code for what I think it should be. Doesnt work though

if narg < 1
HFIG = figure('Name', 'Digital Clock', 'Numbertitle', 'off', 'Position', [400 300 350 100], ...
    'Menubar', 'none', 'Resize', 'on');
 filemenu = uimenu('Label', 'File');
uimenu(filemenu, 'Label', 'Exit', 'Callback', [mfilename, '(''EXIT'')']);

th = text(0.5,0.5,'xxx') ; % retrieve handle
set(gca,'visible','off') ;
set(th,'visible','on','horizontalalignment','center')
while(1),
  c1 = datestr(clock,13) ;
  set(th,'string',c1);% set the string
  pause(.1) ; % break with ctrl-C
  
else
  switch cmd
          case 'EXIT'
          close(HFIG);
  end
end

thanks a lot for the help shwaip

heres the updated code that works now. Also made the font larger.

done = 0;
HFIG = figure('Name', 'Digital Clock', 'Numbertitle', 'off', 'Position', [400 300 350 100], ...
    'Menubar', 'none', 'Resize', 'on');
 filemenu = uimenu('Label', 'File');
uimenu(filemenu, 'Label', 'Exit', 'Callback', 'done=1;');

th = text(0.5,0.5,'xxx','FontSize', 35) ; % retrieve handle
set(gca,'visible','off') ;
set(th,'visible','on','horizontalalignment','center')
while(~done),
    c1 = datestr(clock,13) ;
    set(th,'string',c1);% set the string
    pause(.1) ; % break with ctrl-C
end
close(HFIG);

Alright I have everything how I want it, except for one thing.... I added buttons that show the hour of the other time zones. When you press them, the number appears on the screen. Anyway I want to be able to have a reset button, which starts the program over and clears those numbers. Anyone have some advice for it. Heres the code that I have

% This program is of a clock that shows the current time in other zones of
% the US. The large main numbers is the current time in the Easter timezone. When you press
% the other buttons for the zones(pacific,western,central), it shows the
% hour of that time(not the minutes). This program also has a date feature.

 aboutmenu = uimenu('Label', 'About');
uimenu(filemenu, 'Label', 'Exit', 'Callback', 'done = 1;');

uimenu(aboutmenu, 'Label', 'About', 'Callback', 'about = 1;');
