  • Thanks Mark! Unfortunately the link to the HP support pages, for the Lunar Lander and other HP 30b program examples, is broken, and has been for a few days. I have taken a copy, as best I can, from Google's archived version - but that's only a temporary workaround. (Search for [30b lunar c02047259])
