title: Syntax: Setting the environment variables in Visual Studio 2008
body: <p>I have been trying to add some environment variables in the Visual Studio 2008 for debugging purpose.
  This is because I got this warning:<br></p>
  
  <blockquote>
    <p>Warning    The following environment variables were not found:<br>
    $(DEV_PATH)<br>
    $(APPFRAMEWORK_INC)</p>
  </blockquote>
  
  <p>Here's what I did:
  I went to Project > Properties > Configuration Properties > Debugging > Environment</p>
  
  <p>And I have tried adding the following (one by one):</p>
  
  <pre><code>DEV_PATH="\ProjectName\source\"
  "DEV_PATH=\ProjectName\source\"
  $(DEV_PATH)="\ProjectName\source\"
  "$(DEV_PATH)=\ProjectName\source\"
  </code></pre>
  
  <p>Because this is the path I need to set.<br>
  But unfortunately it does not work.
  What exactly is the syntax?<br>
  As per the link: <a href="http://msdn.microsoft.com/en-us/library/ms173406.aspx" rel="nofollow">http://msdn.microsoft.com/en-us/library/ms173406.aspx</a>, it is:</p>
  
  <pre><code>DEV_PATH=\ProjectName\source
  </code></pre>
  
  <p>But, I need to add multiple such environment variables; so, what must be the separator?
  Also, please don't tell me that I can right-click on "My Computer" and modify the environment variables there; I want these environment variables only temporarily for this workspace specifically.</p>
