You are absolutly right, thank you very much for your insights, they are terrific (like in very good).

I should learn to code first and then try to optimize/use the best thing there is to use... As you point out, it is a must to think more into the problem at hand, as it results that the script I am going to program will not be used heavily and there is not much point to optimize it at this time.

Best regards
