awk append fileA.txt to growing file B.txt

This is appending a column.
My question is fairly simple. I have a program generating data in a form like so:
Code:
1  20
2  22
3  23
4  12
5  43

For ever iteration I'm generating this data. I have the basic idea with
Code:
cut -f 2 fileA.txt | paste -d  >> FileB.txt ????

I want FileB.txt to grow, and my program automatically generates a new filea.txt after every iteration. Thanks for your help guys!
