Good, because there is no such programming language:

Always validate your generated markup: <http://validator.w3.org/>

And the proper syntax is:

  <script type="text/javascript">
    function insertcode (newcode)
    {
      document.forms["newtopic"].elements["msg"].value += newcode;
      return false;
    }
  </script>

  <a href="#" onclick="return insertcode('[i]TEXT[/i] ')"
     ><img src="b2.jpg" height="15" alt="Italic" border="0"></a>

There are even better ways, of course.  Consider generated “button” 
elements, where no navigation will take place when there is insufficient 
client-side script support (as the buttons will not be generated then in the 
first place).

It should have been.

Variable expansion is pointless there.  What is missing is escaping of 
output to prevent code injection:

  <textarea rows="10" cols="50" name="msg" wrap="virtual"><?php
    echo htmlspecialchars($reply);
  ?></textarea>

Adding the “enctype” attribute alone does not cause this problem.  There is 
relevant code that you are not showing.  Please post the public URL of a 
reduced testcase.
