Question Author
smouse, i know I should have no reason to doubt your answer, but I've been unable to cross-check that answer on any website. Did you find the answer on a website, or did you rely on a previous posting, or your own impeccable knowledge? As for the March 12th answer, one has been posted on my previous posting, but that seems equally obscure, and I suspect I may have to go with that (it will come up if you submit the question as if you were posting the question yourself, then check previous answers) but I suppose the compiler has to add a few questions to catch us out. I have had several quizzes returned recently with mistakes I've made, so this year I'm checking evertything out-time permitting, but I don't want to distrust my friends either!
