Hi again. As long as you are considering how DBT imports lists from Scientific Notebook, I figured I'd toss out the following discovery for your consideration. But first a quick disclaimer: To paraphrase Shaw: Those who can do math, do math. Those who can't (but who can do technology) teach TVIs how to use Scientific Notebook. :) I'm looking at the book Learning the Nemeth Braille Code (1987). Based on the examples on pages 62 and 71, it seems that DBT does not correctly handle primes (the apostrophes; not the numbers) when there is also a subscript involved. So x' is rendered correctly, but x'(sub1) is not. See attached. Thanks and take care. Joanie
