WP 34S --> WP 31S

I know there was discussion about reducing the number of registers to 10 to save keystrokes (I personally don't think this is necessary) , but what about the registers X, Y, Z, T, A, B, C, D, I, J, K, and L?

Most of them don't seem to make sense anymore for a non programmable calculator.

Please allow me to disagree. X, ..., D, and L make sense for obvious reasons. I & J are used for distribution parameters. K is an extra general purpose register.

Quote:The only one that really makes sense is L, but wouldn't it be nicer to have a LastX key for this, maybe instead of "FILL"l?

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.

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

Quote:While we are at it, what are the alpha labels used for on the WP31S anyway?

For navigation in catalogs, for example. Think of CONV and CONST if it helps.

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.

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.
