So, Dieter, what is your opinion? (Don't afraid from Hungarian sentences, try to imagine you're in Los Alamos during WWII.)

As you can see, no direct GTO, no indirect addressing, only a simple Euler method with SOLVE.
I think it's a real bug in the SOLVE routine, therefore the real question is that what is the solution if I want to use my calc for these type problem solving? With this bug this calculator is useless when I try to solve more complex examples than "A+B=C".
