Strange behaviour of ANS ?

[Dirk.]

Hello Cyrille,
thank you very much. I did not understand everything you said, but I think the main point of confusion got lost, since this should be easy to fix.

In home mode I use the ANS key to pass an argument to the next function, which is unfortunately a CAS-function. So the calculator should by no means use the ANS of the last calculation done in CAS.

Transferring Objects (e.g. a matrix) between home and CAS by hand is no choice.
It is inconvenient and you have to change the E to e (or vice versa?) which is annoying.
