What's happened over the last five years or so that we get this sort showing up regularly now? Has the internet finally reached the furthest backwaters of the world so that statistically it's inevitable? Yikes.

I have two questions for you: If we're all smart enough that it's worth your while asking questions on this group, why are you arguing instead of trying to understand? That would be foolish. And if we're all so stupid that you can reject our answers out of hand, why are you wasting your time? That would be foolish. There's a common thread to commentary on the above two questions, if you're wise enough to pick up on it. -- Tim Wescott Control systems and communications consulting http://www.wescottdesign.com Need to learn how to apply control theory in your embedded system?

The combined experience of those who've been trying to set you straight surely exceeds your age. A little learning is a dangerous thing. Drink deep or taste not the Perian spring.

It seems to me like he didn't get his ass whooped often enough (or at all) when he was a youngster, and that could happen here (in the USA - I know Eric and where he lives) or in any other country. -- % Randy Yates % "My Shangri-la has gone away, fading like %% Fuquay-Varina, NC % the Beatles on 'Hey Jude'" %%% 919-577-9882 % %%%% <yates@ieee.org> % 'Shangri-La', *A New World Record*, ELO http://www.digitalsignallabs.com

"The individual experience of those who've been trying to set you straight *each* surely exceeds your age" might be closer. But then, either would be reverse age discrimination and unfair. :-) I note there's been no response to any of my posts in this thread .... and I've really been trying to help. Fred
