Nick thank you for the code and for your critical explanations on "how to use this environment".
I also want to thank to Sergy for the code which is also working.

I am trying to upgrade to stata from excel totally. Automation (batch applications) in the initial validation and reshaping of the raw data in stata is a great deal. Thanks again.
