Questions about quitting Octave and exit confirmation dialog

[John W. Eaton]

I'm trying to improve the way Octave behaves when exiting and would like 
to understand what Matlab users might expect.

Does Matlab offer a "confirm before quitting" option for its GUI?

Does that action work when quit is called from a function, or only when 
it is executed at the command line or when Matlab is closed using some 
"exit applcation" button in the GUI?

If confirmation is requested when the quit function is called from a 
function, what does the quit function do?  Here is an example:

  function myquit ()
     quit;
     disp ('foo-i-hithere');
  end

If you call this function and a quit confirmation dialog is shown and 
quitting is NOT confirmed, does execution continue immediately after the 
call to "quit" so that the message displayed?  Or does execution resume 
at the top-level command prompt with no message displayed?  I'm trying 
to determine whether the quit function interrupts the execution of a 
program (similar to Control-C) even if the quit action is not confirmed.

Thanks,
