title: How to source a script file by passing arguments?
body: <p>Say I have a tcl script and I want to pass some arguments to the second script file which is being sourced in the first tcl:</p>
  
  <pre><code>#first tcl file
  
  source second.tcl
  </code></pre>
  
  <p>I want to control the flow of second.tcl from first.tcl and I read that tcl source does not accept arguments. I wonder how I can do then.</p>
