By turns (I use the codes by turns)

[Attila]

Hi,

I have 2 program codes and first I try with the short then with the long and then with the short and so on.

How to say it?

I use the codes by turns.
I use the codes alternately.
I take turns at doing the codes

Just the first two, Attila:

I use the codes by turns.
I use the codes alternately.

If you used these things, alternatively, that means you used them istead of some other things.
