More than 3 years ago (while the WP34s was still under development) I've written a polynomial rootsolver (in fact even several versions, first with Bairstow method, then switching to the better Laguerre method). The final version 'PRS' is a quite long program (520 steps), and it was available in the 'HP Articles Forum' for some time, but I've removed it again from there because of ... (well, I don't want to dredge up this problem). The program is quite sophisticated, it works for polynomials with degrees upto 39 (but only with real coefficients)  if you're interested I could upload it again. Franz
