BTW. I checked Console.Write with an AllocConsole (use FreeConsole to remove this window). Using Console.Write does output to this console. (You do need a restart if you redirected the StdOut.). Can...

Critiquing in general, I'd say that you need to learn dataflow basics. From a cursory look at your block diagram, I'd say all of your sequence structures could be eliminated with a proper...
