Thanks for all the help. Thanks for the sample code also. My debugging is improving.

<br/>> Nice description Herbert! That reminded me of one extra thing. It's kind of hidden but very useful.

<br/>> If you need to get out of a loop but don't want to restart and add a halt, you can click on some place in your code then select "Run To Here" from the pop up menu (right click on windows).
<br/>>
<br/>> That will continue your code until it gets to where the cursor is currently located and resume debugging from that location.
<br/>>
<br/>> That's pretty useful too.
