Almost all messages (around 1.600) of the operating system of the calculator can be translated to another language. These are some screenshots of a calculator where almost all messages show up in French.
You can see here a video of the MultiLanguagePack:
Also the constant library is translated, and the menus as well:
But we think that the most significant advancement of the pack is its treebuilder feature. How many times have you lost time, looking for an equation lost in your file system? And, even when found, did you remember how it worked, and what each variable stood for? Which operating conditions is that equation valid for?
The solution is the Treebuilder: you can prepare your own sets with explanations, and ordered as you want. You can create programs with these menus and even libraries to be further distributed ( a professor can distribute his lessons in an equation tree set)
