Lee Mac, excellent, very good, I like your programming logic, it's a bit similar to mine. I am old because after 43 years programming (43 is not my age) it is difficult to fit the most current logics.
MP, your logic is advanced for me but also good, I said that I did not enjoy joking to see your reaction that was good, congratulations.
