Clear Stack (CLST, CLSTK) and LastX

They left a way to 'do' LASTX by providing the 'last x' in the L register, but that is (maybe for you even) inconvenient because the RCL (or some other method) has to be employed to take advantage of recalling the L reg containing LASTX; I am not sure of the reasons for the change, but there was probably some lively and active discussion about it at the time/

The discussion about this wasn't too active or lively. It came down to:

1. RCL L is exactly the same as LastX in function;
2. RCL L is the same number of key strokes as shift LastX and
3. we saved a shifted keyboard position which are a very scarce resource.
   

I don't regret this change at all.


The 34S doesn't clear last X when doing a clear stack -- although it did for a while. That was a more lively discussion
