Process a sequence of files

EDIT2

I have a question about how can I process a sequence of files. What I've done is extract some information of one file (49271) to write it on a new one ('text'). The problem is I don't know how to do it with a sequence of txt files and also, how can write it on 'text.txt' the result 'line by line'.

    myPath = 'C:\EX\'; 
    a= dir (fullfile(myPath,'*.DIM')); 
    fileNames = { a.name };

     for k = 1:length(fileNames)
           newFileName = [fileNames{k}(1:2) fileNames{k}(4:6) '.txt']; 
           movefile([myPath fileNames{k}], [myPath newFileName]); % rename the files
      end

`% extract information
    fid = fopen('49271.txt', 'r');
    for i = 1:18
        m = fgetl(fid);
    end
    result2 = m([12:19]);
    fid = fopen('49271.txt', 'r');
    for i = 1:30
        p = fgetl(fid);
    end
    result3 = p([12:19]);
    fid = fopen('49271.txt', 'r');
    for i = 1:31
        q = fgetl(fid);
    end
    result4 = q([12:20]);
    fid = fopen('49271.txt', 'r');
    for i = 1:19
        r = fgetl(fid);
    end
    result5 = r([12:20]);

   % copy information in a new variable (of one line)
  load('text.txt');   
  text= {newFileName, result2, result3, result4, result5}

I'm trying with the following code but I don't know how to write it:

    filePattern=fullfile( myPath,'*.txt');
    txtFiles= dir(filePattern);

    for k = 1:length(txtFiles)
    baseFileName=txtFiles(k).name;
    fullFileName= fullfile(myPath,baseFileName);
    fid=fopen('filePattern', 'r');
    for i = 1:18
        m = fgetl(fid);
    end
    result2 = m([12:19]);

      end

Thanks in advance!

filePattern=fullfile( myPath,'*.txt');
txtFiles= dir(filePattern);
for k = 1:length(txtFiles.names),    
    fullFileName=fullfile(myPath,txtFiles(k).name);
    fid=fopen(fullFileName, 'r');
    for i = 1:18
        m{i} = fgetl(fid);
    end
    result2 = m{12:18};
end

You're a crack! Thanks so much Pedro, it works! ;)

It is tricky to skip characters in text files without reading them. It is much easier to read the text and throw away what you do not want.

Hi Walter! Yes, you were right. I've changed the way to do it and I've edited the question again.
