Cuvee RPN-67 & Complex mode

[Nigel (UK)]

The problem is that in complex mode pressing ENTER copies both the X and Y registers into Z and T, so you can’t enter numbers one at a time. I tried to enter numbers in complex mode using x<>y, like this:
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!
