Yeah, I've seen that as well. For i = 0 to 0 will still produce one cycle through the loop.

I've not scoped the signal, but to be honest I don't know what I'm looking for! - I've never done it before, but it would be valuable for me to learn.

I'll do some reserach on the web to learn what to look for and scope it tonight after work. This should be very valuable - thanks!
