How to write text in the middle of a file in vbscript? : <p>I would like to know how to write text in a middle of a file in vbscript.
The text file has 2 lines, one line for the name of the output and the second of the value. The outputs separated by ";"
For example : 
Before insert text, the text file contain - </p>

<blockquote>
  <p>mem1;mem2;mem3;<br>
  0.15;15.5;12.3;</p>
</blockquote>

<p>After insert new text - </p>

<blockquote>
  <p>mem1;mem2;mem3;mem4<br>

</blockquote>
