I leave them there. If I was to go through and remove them, it would defeat the entire point of the conditional compile statements :) They are not compiled in at all of they are not specified so don't have any negative effect on the code. -- Dee Earley (dee.earley(a)icode.co.uk) i-Catcher Development Team iCode Systems

Most of my "conditions" aren't known at compile time. 16 or 32-bits were, of course. I also use it sometimes to branch to different code if I'm in VBA than in VB5/6. But that's just the way I tend to work, which I recognize everyone does differently. It's a great thing to know about. Like Choose(). I don't use that a lot, either, but I have on occassion and liked it when I did. -- ..NET: It's About Trust! http://vfred.mvps.org

For those things that only replicate in an EXE, you can include oodles of code to output intermediate results, and so on, but only when the switch is thrown at compile time. Again, it's not something I do often, but have found invaluable at times in the past. -- ..NET: It's About Trust! http://vfred.mvps.org

It's basically a text editor with tabs and TreeView on the left to allow you to type text in categories and save everything in one file. You can name the tabs and categories whatever you wish, they are saved in the file. See the screenshots here: http://www.tranglos.com/free/keynote_screenshot.html http://www.tranglos.com/free/keynote.html It was discontinued by the author, but others continued its development.
