While on the HP-17BII, you can enter a partial solver equation, exit and then go back and edit it until you get it right. What Bill is referring to is a truly maddening feature unique to the 19b/19bii, AFAIK. On a 17b/17bii, when you are done entering your equation you press CALC. If an error is detected at that point, and you don't want to take the time to figure it out, you can press EXIT and your equation is still saved, with the error, for later correction. On the 19b, an equation with an error cannot be saved. If you don't correct it when it first happens, as soon as you press EXIT your equation is erased and gone, and all the entry work you just did is lost forever. This is more of a problem when you are entering very long equations, obviously. On a 17b you can enter a long equation in steps or "stubs", to check parts of it as you go, but you can't do that on the 19b. |
