Extracting values from vectors/matrices in home

I know you specified not using variables, but global variables exist whether you use them or not, so I say go ahead and use them.

I use global variables for values I want to save for future use, and there are only 10 already defined global variables for matrices, I know I could try to always let one of them unused so that I can use it for this scope, but then they will be 9...

Storing a vector/matrix in a variable always implies more steps.

So the way proposed by Dale is probably the best one, as I can assign "col()" to a user key.
It would be nice to use col(ans,2), but it looks like "col" uses the Cas Ans and not the home one.
Same thing with CAS("Ans(2)"), this is quite logical as I am using CAS()

Is there a way to use col() in RPN mode?
