All you do is run the debugview program before you run your AFL. You'll get
a window that you leave running.
Then in your AFL you sprinkle _Trace( ) statements at critical points
and inside the parens you put some literals to tell you what you're looking
at and after the literal you put in the proper function to display a
variable that you want to examine.
The help file for _Trace has a couple of examples, once of which is:
http://www.amibroker.com/library/detail.php?id=586&hilite=_TRACE
When you run your program you'll see the results of the _Trace's in the
debugview window.
Don't make it complicated - it isn't - its VERY simple.
