title: What is ".load" in .load sos?
body: <p>In Visual Studio I use <code>.load sos</code> in the Immediate Window to load sos.dll. What is this '.load'? Is there some description for it?</p>
  
  <p>In the Immediate Window I Can:
  Evaluate an expression (<code>? varA</code>), execute program command (<code>varA=1</code>)  or execute VS commad (<code>&gt;cmd</code>). Where is .load at this scheme? Can it be used on some other place (Command Window Macro)?</p>
