How do i print output message on reply log in TureClient Script?

Hi All,

I am new TureClinet user and still trying to get a hang of it. 

I have created a true client script  for our internal web application and would like to run that for 10 itereations. How do i print output message (iteration number) on reply log or interactive replay log window in TureClient Script when running from VUgen?

Thank you in adavance!
