Reading data from textarea line by line - need to loop

I'm writing a script in VBScript for a classic ASP application (NOT ASP.NET), and I hope someone here has succeeded in this.

What I'm doing involves a form which posts to a script which will take the data and compose/send an email using CDONTS (it's on a Win2K server, IIS 5.0). The idea is to be able to paste a list of email addresses separated by \n into the textarea.  When the form is submitted, the handling script uses a Do While... Loop to extract the first line (email address) from the textarea, compose and send an email message, and then loop to the second line, compose and send a message, loop, etc. until it reaches the end.

I have this successfully working using a text file on the server containing the email addresses using the FileScriptingObject in ASP (opening the file for reading using OpenAsTextStream) instead of the textarea method, and it works fine.  There's nothing wrong with the script itself at this point, other that that I can't figure out how to extract the contents of the textarea one line at a time so that I can use the Do While... Loop.

I know I could make it a two step process by writing the contents of the textarea to a text file on the server, and then using the OpenAsTextStream method to call it back into the script.  It just seems like I should be able to do this without having to write to a file.

Any ideas?  I'm probably missing something obvious, but 20 pages of a Google search didn't give me anything.

<%@language="javascript"%>
<% //This is hielo.asp



if( "undefined" != String(Request("emailList")) )
{
      var addresses = String(Request("emailList"));
      addresses = addresses.split("\n");

      var emailObj = null;

      for(var i=0; i < addresses.length; ++i)
      {
            if(addresses[i].indexOf("@") > -1)
            {
                  var emailObj = Server.CreateObject("CDONTS.NewMail");
                  emailObj.To = addresses[i];
                  emailObj.From="you@yourdomain.com";
                  emailObj.Body="Test";
                  emailObj.BodyFormat=0;//0=HTML;1=plaintext
                  emailObj.send();
                  emailObj=null;
            }
      }
}
%>


Your form will need the following textarea:
<form action="hielo.asp" method="post">
      <textarea name="emailList"></textarea>
      <input type="submit" name="send" value="Submit"/>
</form>

On the page that is processing your form (SendMail.asp or whatever)

  'Your send to form field
  SendToList = Request("SendTo")
  'Chr(13) is a line break
  SendToArrr = Split(SentToList,chr(13))
  For x = 0 to UBound(SendToArr)
     'All your mail sending code
     'The SendTo address will be
     'SendToArr(x)
  Next

Thanks to swinslow... hit on exactly what I was looking for.  I figured that splitting with the newline and writing the texarea contents to an array was going to be the answer, but for some reason it just wasn't clicking for me.
