The VFP help isn't that great on this. As normal, The Hackers Guide to VFP has a much better explaination. If you don't have it, go get it from www.Hentzenwerke.com. If your time is worth more than .10/hour, you should be able to save the cost of the book in a week or so.

The include file's defined constants are processed at compile time in a search-and-replace fashion in your code. The compiled code has no reference to these constants. I never noticed this about the debugger before, but I assume it skips the #include line because that line doesn't actually exist in the compiled code.
