How do I display the value of dynamic variables in the testlog.

To audience:

The short and exact answer to the question been asked is : "No, this is not possible".

A little bit more extended answer is that this is not possible because not really required for load testing.

The complete status update is that it appeared that the actual task that caused this question was not actually related to the load testing but to the performance measurement and thus it is better to do it using more appropriate tools like profilers (e.g. AQTime).
