Code:

r:=[2.5, 2, 0.8];
r(1)

I just tested this on the virtual calculator build 2.1.13325 (2020 1 16)

This just stores the whole vector - take a look at your calculators memory.
It does not extract and store the element 2.5

Mine calculator software has just been upgraded to version
2.1.14425 (2020 01 16)

I read your help post above. I find it very useful. So being surprised of this one
answer from you. It could be different on your calculator. -
But don't think it is.
