Cuvee RPN-67 & Complex mode

4 x<>y 3 ENTER 5 x<>y 9 MULTIPLY
But when the final 9 is pressed, the 5 in Y is copied into T!

It helps to have the stack contents display visible while experimenting. It is then very clear when something isn’t working!

Thanks. So, outside of testing the setting with

x (other than 0 or 1) g OP CPX MODE to see or test the setting, what’s the purpose of

setting or clearing Complex mode with the g OP CPX MODE operation?
