RE: [34S] Proposal for Entry RPN mode with dynamic stack
As an addendum to my previous post, and to be complete:

Unary operators are 'explicit' special purpose 'enter' keys.

In other words, as an example, the [+] key does three things explicitly (by definition) in the new setup (internally):

1) presses the 'enter' key {command processing, 'enters' from input buffer into X}

2) operation {adds Y into X}

3) 'drops' the stack


PS There should be a key (op code) that toggles the auto 'lift' or 'drop' explicitly. We toggle auto drop 'off' for situations where we want constants (constant in Y). We toggle auto 'lift' off when we want explicit control over register manipulation (mostly in programming mode).

Kind regards,
