Meaning of the dollar sign($)
<p>I was reading up on socket programming and i saw a sample code. 
The thing i dont understand is the meaning of the dollar sign($).</p>

<pre><code>byte[] outStream = System.Text.Encoding.ASCII.GetBytes(massConvoMsg + "$");
</code></pre>

<p>Does it mean that it is a string? or?</p>

<p>Thank you.</p>
