Saving output of every loop to a file

[ksr]

hello guys,
i am trying to save output of a every looping to a file, with the following
code

start = 1;
stop = win_length;
[y, fs] = wavread("eg.wav");
    for i=1:win_length
         y = abs(fft(x(start:stop).*fft_win));
         start = stop +1;
         stop = stop + win_length;
         save('-text',dbout(i).txt, 'y');
    end

but the ouput in dbout(i), is expected to save like 
dbout(1).txt
dbout(2).txt
dbout(3).txt
.
.
.

but its not happening like that
please help me how to save this to a new file for every looping 
Thanks in advance....
