How do you write data to a measurement file outside of a while loop?

[drneil]

We are using a while loop to run a control system and would like to acquire the feedback and control signals continuously (until we manually stop).  However, when we place the "write to measurement file" inside the while loop, it restarts saving the file on each loop rather than continuously storing the data.  When we place the "write to measurement file" outside the while loop, we don't get any data stored.  How should this be structured?
