How to put data into a file?

Not entirely sure how to elaborate on the title.

example:

code:

var number: int put "enter number" get number

After which I would like to put the variable number into A.txt

I know there are examples of how to do this on the site, I just forget what I searched before to find them. A nudge in the right direction would be great.
