title: Find the line & edit it
body: <p>I posted another one on this,, but i had to edit it really much...</p>
  
  <p>What the thing bassicly is that a Batch (Maybe including VBScript) can find line 29 in a txtfile... it should edit this line.</p>
  
  <p>If line 29 is like this: 'option=21'   it should change it to 'option=22'</p>
  
  <p>the problem is that this line is located more in the file. so it should just edit line 29...</p>
  
  <p>How-to???</p>
  
  <p>[please no custom programs;;; it should be done by every user without installing something OK.]</p>
