how to write in the text file?

hi all, the following code is for writing all of data file names into text file, the problem is the name are not written in the text sequentially

 clear 
 FN1 = 'JDA';
z   = '0',
mn  = 1:12;
yr  = 9:13;
ext = '.ohh';
 for k = 1:numel(yr);
       if yr==9
          tmp = sprintf('%s%s%03d%02d%s',FN1,z,yr(k),mn(k),ext)
          fid = fopen(tmp,'rt'); 
       end
     tmp = sprintf('%s%03d%02d%s',FN1,yr(k),mn(k),ext)
     fid = fopen(tmp,'rt');
    end
          filename = fopen('JDAraw.txt','w');
           fprintf(fid,tmp);

If anyone can correct this for me, I'll appreciate the help.

FN1 = 'JDA';
mn  = 1:12;
yr  = 9:13;
ext = '.ohh';

format = sprintf('%s%%03d%%02d%s\n', FN1, ext);          
data = [yr; mn(1:numel(yr))];                
text = sprintf(format, data(:))

fid = fopen('JDAraw.txt','w');
fprintf(fid, '%s', text)
fclose(fid)

It worked, but it does not count the other months only the first one from each year

[Thorsten]

If you want filenames for 12 month for each year, use

data = [reshape(repmat(yr, [12 1]), 1, []); ...
        repmat(mn, 1, numel(yr))];
