LOGO/TURTLE/TORTUGA MODE on HP Prime Graphing Calculator

[parisse]

Indeed, it's gaining in popularity here in France as a transition between Scratch and Python(-like) programming. Xcas turtle commands would be straightforward to port on the Prime, but interface would require some work and it would probably be easier to implement independantly from the CAS, because in the Xcas implementation computation and drawing are done in 2 independant steps, which is much more complicated than required on a calculator (this limits the number of turtle instructions to 512 on the Casio Prizm because of the memory available).
