Well Patricia that was really easy and very quick, thank you. And thank you Stingo.
Sadly, what it's done is to give me the book with no paragraphs or pagination at all. May be that it's just not a good .lit copy I started with. Can't remember where I got it.
Not important as I have a proper prc copy of Dead Souls anyway, but I was trying to establish the simplest routine I could adopt reliably for the future when I do need to convert a lit book.
