<p>What's the ASP equivalent to PHP's <code>.=</code> when concatenating strings? I'm referring to asp NOT asp.net.</p>

<p>I meant to specify that I'm in a for-loop. So I want to know the equivalent for <code>.=</code> (in php) not standard concatenation.</p>

<p><em>Example:</em></p>

<pre><code>For Each Item In Request.Form
    If (Item = "service") then 
        For x=1 To Request.Form(item).Count
            service = "&amp;service="&amp;Request.Form(Item)(x)
        Next
    End If
Next
</code></pre>

In VBScript:
```
```
Variable = Variable & "something more"
```
```
In JScript I believe you can use:
```
```
variable += "something more";
```
```
Specifically:
```
```
service = service & "&service=" & Request.Form(Item)(x)
```
```
assuming you want your result to look something like...
```
```
&service=blah1&service=blah2&service=blah3
```
```
Though you may need to URL encode your Request.Form(Item)(x) values because any "&" (and other characters) could really muck up what you are trying to do.  Also be careful when using unsanitized input like this directly from an HTML form, its very dangerous.
