HP-42s Entering 4 complex numbers on the stack

[Vincent Weber]

Good point about LASTX. What do you think of my way?

Regarding the 32S/32SII, I like the simplicity or the complex numbers handling, but I think it is half-baked:
-A stack reduced to 2 elements;
-No way to operate this stack like the normal one: no complex X<>, lastX,etc...;
-Missing math functions, e.g. reverse trigs.

All in all, quite difficult to write a program that operates seemlessly on both real and complex numbers!
