Geoff, I have been working on making a both creator and reader 'ebooks', so a I have needed paginating a 'book' from a text file. The best solution I have found is to use the pageheights property, as Scott suggests in other response, because it makes the work very well without effort, but it is not so fast as you want. Finding a particular chunk may be done with a simple 'find' command --very fast in 100 pages or bigger books. Or you have to 'index' the text to know in which pages a particular word appears, but this a process that takes more time to build the index. Regards, Jose Luis ------------- José L.
