Doubts about the Home View

[Han]

Tim, I believe he is referring to RPN mode vs non-RPN mode. In non-RPN mode, the history is the same as the Home view. In RPN mode, the history is actually a completely separate history from the Home view.

Technically, there are three histories: RPN, Home, and CAS. RPN is completely separate from Home and CAS (although I think the OP was referring to changing input modes that force switches between the RPN history and the Home history).
