Thanks for the kind words. (Please notice that there is no need to quote a large posting completely.)

The flash library is an assortment of keystroke programs. Their commented source code can be found in the library folder on SourceForge.

All the built-in stuff can be divided in two groups:

1. Native code (compiled C) is used for the infrastructure code (which can be seen as the operating system) and the basic math stuff. Some more involved mathematical functions are coded in C for performance reasons.

2. XROM which is nothing more than keystroke programs. Most XROM code has a special environment (register space independent from user memory, double precision as default, proper handling of LastX, lack of labels in exchange for absolute jumps, etc.). If you want to learn more read the XROM sources!
