Z LIGHTS 0.3   (details) Prime ENG   4KB/6KB
Prime's answer to mobile phone flashlights. Given that the HP Prime has no external accessible lights, this program may be of little practical use, unless the lights go out while you are using your calculator. The design aim is a compromise between maximizing the limited illumination available, and including some information that a flashlight would not (the time the light was activated).
