title: Equivalent to cmd 'call' command?
body: <p>When creating a cmd/batch script (e.g. <code>parent.bat</code>), it is possible to use the 'call' command to call another batch file (e.g. <code>child.bat</code>). The instructions found in the <code>child.bat</code> would run as part of the <code>parent.bat</code>.
  Any variables that the <code>parent.bat</code> would use, the <code>child.bat</code> could use and vice versa.</p>
  
  <p>Is it possible to pass through variables from the <code>parent.ps1</code> to a <code>child.ps1</code> and vice versa in PowerShell?</p>
