history of the 4-level stack

Hello RPN fans,

And about the statement more than 4 level stacks would make memorization of stack contents difficult for most people (read that far more than once here): True for sure but actually nobody needs memorizing all stack contents unless doing high level stack gymnastics. You just have to know how the stack works and that you can trust your intermediate results pop up again just at the right time - that's all. I never had the ambition to memorize all stack contents - nonetheless RPN works for me as well, be it with 4 or 8 levels.

Your argument doesn't hold, if you work out a program with such a stack. I often had to draw a sketch where I could see which value is in which stack place . It is a kind of sadism to program stack manipulation over lets say six stack places (with my preferred HP 50g).
