further support and sympathy to RPN mode from Turkey.
But can anybody help (or is there a way to undo) a process that is done wrongly? I could do it in Algebraic mode.

I can understand that part, but I admit that as a long-time HP-41C user the emphasis on algebraic in the manuals is annoying. It means everything takes so long to explain, they always give the algebraic first (even though they have been careful to make RPN quicker, entering lists etc), and sometimes don't explain the RPN way at all. I can understand the commercial reasons for giving an algebraic mode, but could wish they didn't emphasise it so much.

One thing confused me about the 50g. It's apparent schizophrenic agebraic vs RPN operation.
For example, I want to define a function. I see a stack, so I know I am in RPN mode. But I only see how to type it in as algebraic to define it.
Can someone clarify how this works?

However, in this case I think it does make sense. RPN means you don't wait till the end to evaluate things, you do it immediately with what is on the stack. If you want to enter an function or equation, however, you do want it to do everything at the end, and it also means you can readily check what you have in the display with what you want. Of course, if you programmed that function it would be more the RPN way.
At least, that's how I see it. In spite of my criticism on this, btw, I'm very impressed with the 50g, I hadn't expected so much beyond my old 41c.
