title: Substring of a variant string
body: <p>I have the following return of a printer:</p>
  
  <pre><code>{Ta005000000000000000000F     00000000000000000I     00000000000000000N     00000000000000000FS    00000000000000000IS    00000000000000000NS    00000000000000000}
  </code></pre>
  
  <p>Ok, I need to save, in a list, the return in parts. </p>
  
  <p>e.g.</p>
  
  <pre><code>[0] "Ta005000000000000000000F" 
  [1] "00000000000000000I"
  [2] "00000000000000000N"
  ...
  </code></pre>
  
  <p>The problem is that the number of characters varies.
  A tried to make it going into the 'space', taking the substring, but failed...</p>
  
  <p>Any suggestion?</p>
