Strange behaviour of ANS ?

[Dirk.]

    Hello,
took me a while to see what happens -> Maybe not easy to reproduce.

For me it seems CAS.l2norm(Ans) is not always catching the last/shown value of Ans.

Example:
[1 2] ENTER
-> [1 2]

Ans
-> [1 2]

CAS.l2norm[Ans]
-> Sometimes output seems to be a result from an older vector or even complete garbage, for example 0 or a complex number...


Do I missunderstand something?
   

I made some screenshot, but I don't know how to insert it into the post. It shows the following situation:

[3 6] ENTER -> [3 6]
Ans ENTER -> [3 6]
CAS.l2norm(Ans) -> 3*sqrt(5)

[1 2] ENTER -> [1 2]
Ans ENTER -> [1 2]
CAS.l2norm(Ans) -> 3*sqrt(5)

Before Clear (Shift ESC) I even manged to get some complex number as a result of CAS.l2norm(Ans)
