Enter vs. =

[Jlouis]

I don't think time has changed the results of the article.

RPN is still RPN and algebraic is still algebraic.

What have changed is calculators with bigger display and the use of the so called "pretty print" or text book entry or whatever, where one can entry in the calculator display an exact expression or formula like in a text book.

But, IMHO, this is good for entry equations. For long expressions number crushing nothing beats RPN and again, the research is still relevant, IMHO.

Thanks for bring this from the past, I was not aware of that, but I've already knew the results by personal experience.

Cheers
