PascalScript: Looking for something like OnBeforeLineExec and OnAfterLineExec
<p>I am writing a small IDE with Single Steps using the Debugdemo.
Now I need an Event before and after a line is executed.
I would like to disable my Editor while the current Line is executed.
I found the OnLine Event but did not find out in what cases it is fired or how I can use it.
Any hints are welcome.</p>

<p>Greetings Klaus</p>
