Hi all,

sorry, I haven't been here in ages because my new job and going to business school doesn't leave much time for anything else.

I need your help. My exam is on thursday and the 17bII+ I've stored my equations in died. I have a 50g I wanted to use in next year's exam, but now it seems I have to use it next week already. And I know almost nothing about that device.

I need to input all my equations quickly. To do so, I can either use TreeBrowserBuilder or Pequm but have difficulties with both programs.

TBB lets me create a structure and equations once and I can start TB and solve the equations. However, every time I exit TB the calculator freezes. The same thing happens when using TBED or TBNEW.

Pequm works, but equations are always solved for X and I often need the result of an equation, later. So if I for example solve equations for DBII and DBIII, with TBB I could later use those vars to calculate DBIII-DBII.

With Pequm instead of DBII and DBIII I'd get X and X and can't do further calculations with those variables. Is that true?

Which of those two problems is easier to solve? And how could I solve it?

Thanks a lot.

Timo, now slightly less panicking because being in good hands
