Hello Jean Giraud,

Thanks again for your attention to my questions.

Could you help me with one more question?

Why can't I calculate in the file "Nikolai roots.sm"?

Clicking the "Recalculate page" button gives the error "F() - function isn't defined.".

Is this a problem in different versions of the program or a problem in another?

Total and impressive disaster !
Possibly, your Smath installation is defective ?
Possibly, your Smath version is kaput ?
On that last point, Designers can confirm.
I will make a PDF, so you will be able to code/sanity.
Cheers ... Jean.

... run that test version. At worst, code as given.
You can'y escape eval(x*Bessel(1,x)-1.01*Bessel(0,x))
