Sorry, I'm saddened to think you've both missed the main point: if you have to turn away from the code to (maybe find and) look at [** see below], readability has already been damaged. You should be able to understand the code just by reading it, without having to consult endnotes. [** some (admittedly admirable) cross-reference list] Brent Longborough -- Sent from my typewriter - please forgive any malformed glyphs. -- (I omitted my "confidential" postamble here since it has no conceivable basis in law and would add twenty redundant lines to the thread.)
