title: Randomly replacement in textfile via batch
body: <p>I have a textfile (.txt), that is built like this:</p>
  
  <pre><code>;ARPE for Ariminum
  event   plague  ARPE_RIDaba
  date    RND summer
  position    96, 81
  
  ;ARPE for Tara
  event   plague  ARPE_RIDbbg
  date    RND summer
  position    34, 143
  </code></pre>
  
  <p>Now I need a batch script, which will replace all the "RND" in my file with a random number between 1 and 250 (no comma, only whole numbers). But I do <strong>not</strong> want every RND to become the same. I want each RND to be assigned random and independent from the others. Also, the text file is coded in UTF-8 without BOM and it <strong>must</strong> stay like this.</p>
  
  <p>Is there any solution for that?</p>
