Different note app / way to store often used formulas / how to start programming

[debrouxl]

Yup, the same OS 3.0.1.753 in April 2011 added some (then-undocumented) Lua programming capability to the whole Nspire series, but as I wrote:

Quote:a platform-specific Lua with a proprietary event-driven API but no ability to read or write files...

Among others, we've recently had to work around against that crippling, for the TI-Planet document generator (mViewer GX Creator). A much more efficient storage format could have been used if the Nspire's proprietary Lua could read from the filesystem
That said, the Prime document format is even slightly more inefficient...
