To Jim P and Charles Kenyon

Thank you both very much for your advice - and my apologies for loading such a rant in the first place: I accept this is the wrong forum for such a general anathema, and I should have thought more carefully.

I will follow up the references you have given - particularly of course Mr Kenyon's tutorial on how to use styles (when I can find the time from correcting and cursing).

Then I will probably come back with some more questions, but thanks again.
