Valentin, your solution of the Step the Third is really great!

I didn't known that it was possible to evaluate long expressions in that way.
I learnt something today (yes, it's still possible to learn new things, after more than 30 years of HP71 usage), thanks again:

- That VAL and FNROOT (and INTEGRAL) can deal with expressions limited only by available RAM, not by the 96-character limit of the command line.

How did you come to discover this possibility? By chance or rational exploration?

Of course, it is only possible thanks to the VAL function of the HP71, that is actually an expression evaluation function, rather than the classic Basic VAL function that can only convert a number from its ASCII representation.
For instance, the solution is not applicable to the HP75.

The HP71 design team did a great job at the time.
