I'm sorry if this is a basic question, but is the source code for the implementation of calculator functions available? For Soft Key functions, its great that holding the key reveals the source code. How can I do this for other functions? For example, I was having trouble with the function 'repeat' for arrays and I wanted to look at it's implementation to understand how it was supposed to work.

More importantly, to really learn more about extending ND1, source code of it's core functions (as implemented in JavaScript, RPL or otherwise) would be of great benefit from a learning perspective.

Thanks
