Hi Nigel,

thanks a lot for your answer. HP prime really seems to have a problem here. I tried it once more and after about an hour there came a message like "A problem occured to HP Prime and it will switch off in 3 seconds". Then it switched off. If switched on again everything is normal, no message. So normally you will not see it.

So I think I have to program it step by step, e.g. using Gauss' or Romberg's method.
