Any particular equation(s) or set(s) -- or all of them? Have you tried starting in an empty new directory? [r->] [OFF]

But who wants to need a week's study to find out how to even be able to start using a major selling feature? Since menus are defaulted to "choose" when the calc comes out of the box, this means that the Equation library won't work out of the box! (even when RPN mode is set). Wouldn't it be a good idea to have the Equation library *automatically* set the necessary mode(s) [both RPN and SoftMenus], to give new purchasers a smoother experience? Surely any marketing types at HP would appreciate that, instead of having new customers take their new calcs right back to a flustered sales clerk at the store, and trade for other brands which work as delivered? After all, the CAS forces (often undesired) mode changes all the time; why not let the Equation library set a (usually more desirable) mode, expecially if there's no other way that it can work at all?

I'm looking at this from a different perpective: fighting illiteracy. People don't read these days when the information is right there on the first page of the Equation Library chapter... "Flag 117 should be set whenever you use the numeric solver to solve equations in the equations library." JY

You (and others) have done a wonderful job going this far, and I hope that anything which may lead it to be appreciated by more potential purchasers might be an advantage for you, too. Thanks for the product which you (with Cyrille and others) made, for all the recent developments and improvements, and I hope it expands to receive its maximum possible appreciation and market share.
