automation and for loops

[Jonas Amhest]

hi all, 

i'm using octave 3.2 on windows xp. 
i have a lot of files i need to load and save, but it has to be automated. 
the files have headers, data, and footers. i know how to open these but i want 
to incorporate a loop where the file is loaded and saved to a separate file or 
even just have the data saved to a separate variable through each loop.

here're are two example files:

new00.txt

asdf
asdf
1385.00 5585
2446.34 95456.74
3234.35 2343456.04
4564    53456345
5797    83456
asdf


and 

new01.txt


asdf
asdf
1385.00 5585
2446.34 95456.74
3234.35 2343456.04
4564    53456345
5797    83456
asdf


to open the files i'm using this code so that it skips the headers and footers 
and makes a matrix out of my data:

data = []; 
fid = fopen('ref00.txt'); 
line_string = fgetl(fid);   # reads one line of the file into a string
while (line_string != -1)   # makes sure its not eof
  [line_data, count] = sscanf(line_string, '%f %f');  # tries to parse string; 
f=decimal notation
  if (count == 2)   # if its successful (finds 2 integers)
    data = [data;line_data'];   # append it to your data variable
  end
  line_string = fgetl(fid);
end
fclose(fid);


my matrix is saved into the variable data. i was trying to put the code above 
into a for loop that saves new00.txt into 'data00' and new01.txt into 'data01'
based off of this code:

files=dir('*.txt');
for i=1:length(files)
        eval(['load ' files(i).name ' -ascii']);
end



my attempt at this was:

for i=1:length(files)
fid = fopen(files); 
line_string = fgetl(fid);   # reads one line of the file into a string
while (line_string != -1)   # makes sure its not eof
  [line_data, count] = sscanf(line_string, '%f %f');  # tries to parse string; 
f=decimal notation
  if (count == 2)   # if its successful (finds 2 integers)
    data(i) = [data;line_data'];   # append it to your data variable
  end
  line_string = fgetl(fid);
end
fclose(fid);
end

but i keep getting an error about double_value () : :wrong type argument 
'struct'



any help is greatly appreciated!
