you can include a number in a filename using "sprintf" 

for ii = 1:128

 input_file_name  = sprintf ("input_file_%3.3d.dat", ii);
 output_file_name = sprintf ("output_file_%3.3d.dat", ii);
 fid_in  = fopen (input_file_name, "r");
 fid_out = fopen (input_file_name, "w");

 %% do stuff

 fclose (fid_in);
 fclose (fid_out);

endfor

for more info type "help sprintf" or "doc sprintf" at the octave prompt.
