I have been working on fixing a bug on slash. I am having no luck If you do lou_allround and do3/4 you will see the problem Starts with: 3/4 Translates to #c/d Back translates to: 3st4 I have tried adding a rule of Noback midnum / 34 even though lou_trace shows it as a midnum my rule doesn't seem to run. Heck I even tried sticking noback in the chardef file for Noback math / 34 No such luck there either. Any ideas why this is not working? Ken
