What? Not necessary, not even desirable? You must be kidding. I am using LastX in my programs (41C, 35s, 34s) all the time. It's an absolutely useful tool that simplifies many programs – just as it does in manual calculations. Without LastX (or the L-register on the 34s) most of my programs would be significantly longer and more registers for intermediate results were required.
