sorry, keith, but i don't wanna have this dialog with you. you're talking about this in a general "theoretical" sense, which allows you to be extremely vague and nonspecific. on my side, i have actual code that i have already written, which runs and does the job well and uses few resources. so, you know, nothing here is "broken", so i don't need to "fix" it, even if i thought you had "the cure", which i don't. i was communicating something important to roger, and i trust that he understands it, or will ask me if he doesn't. -bowerbird
