Hi Max, that's what I thought it would be. My problem though, is that I'm not quite sure what I should be looking for to find the correct #pragma or declaration (heck, I hadn't even heard of #pragmas!). I will keep looking, but if anyone can remember the correct directive then please let me know :)
