Hey Ken, Thanks much. I took classes in it ages ago, but haven't looked at assembly language since the third year of my undergraduate studies. As for your comments regarding the fact that people should know it, I couldn't agree more! I just wish I didn't have to teach it that's all as I've absolutely no interest in the stuff whatsoever! *smile* Cheers, Dónal __________ View the list's information and change your settings at //www.freelists.org/list/programmingblind
