WP 34S --> WP 31S

Ok, allow me to disagree as well
While X, Y, Z, T and T need to be present for obvious reasons, there is no real need for them to be accessible via STO and RCL. Stack manipulations are useful for programming, aren't they?
We probably won't agree on A, B, C and D. They are for the 8 level stack, which in my opinion is only necessary for complex mode. I assumed an 8 level stack wasn't available on the WP32s as it (regrettably) doesn't support complex numbers. But I now noticed it is available.

Quote:The special registers can be addressed in the same way as on the WP34s. However it is a bit odd to find that "ENTER" puts the WP31S into alpha mode without mentioning alpha mode on the key.

Quote:There will be a manual for the 31S explaining also that.

I'm looking forward to the manual

Quote:Maybe using registers A to Z (as on the HP32S) and a dedicated LastX would be an option?
That would save keystrokes as well but preserve more then 10 registers for general use.

Quote:The 31S is a strict subset of the 34S (one and only exception is UNDO). We feature neither registers E through H nor M through S nor U, V, W on the 34S. For an entry-level non-programmable scientific, 13 to 17 registers are sufficient IMHO. And comparing f LASTx to RCL L, I don't see where you save keystrokes.

The keystrokes would of course be saved by for example typing <RCL> <V> instead of something like <RCL> <0> <7>.
No keystrokes saved on LastX
