Evaluation of variables in 50g

[Didier Lachieze]

Well I’m not an expert in RPL, but today if I do:

Code:

'X^2' 'A' STO
'X+1' 'B' STO
2 'X' STO

Then executing << A B + >> returns 'X^2+(X+1)' not 7 as it would with your proposed change if I understand it correctly. This seems to be a quite significant change of the symbolic operations.
I will let RPL gurus (and I know there are a few on this forum) provide more inputs.

EDIT: Btw, do you know how this is done in RPL/2?
