Hi again. I'm still comparing what Learning the Nemeth Braille Code (1987) states should be true with what occurs when you use Scientific Notebook and DBT. Based on this, it appears that * when a number has a modifier/decoration such as a line or a dot over it to represent recurrence, AND * when that number begins with a decimal point (i.e. .3 rather than 1.3) The number sign that the code book indicates should be present is missing. See attached SN document. Take care. Joanie
