title: IDL reading in multiple file
body: <p>I'm relative new to IDL and I need to achieve the following:
  Basically all I have to do is to read in different file and create different arrays while reading them.</p>
  
  <p>So I was thinking something like:</p>
  
  <pre><code>files=dialog_pickfile(/multi, filter=filter, path=path, title=title)
  n_files=n_elements(files)
  for i=0, n_files-1 do begin
  openr, lun, /get_lun, files[i]
  readf, lun, data
  </code></pre>
  
  <p>But at this point how to create different array by keeping track of the e.g. name of the file.</p>
  
  <p>For instance:</p>
  
  <pre><code>arrayfile1(i,j,k)=
  arrayfile2(i,j,k)=
  </code></pre>
  
  <p>and so on.</p>
  
  <p>Hope this is clear,
  Best. </p>
