>a long non understandable story you post here.

Sorry if my English is not up to the mark. You do not understand that you can code - in my case, vfp, sql engines or python - whilst having no strong background in system engineering. I stop it. But I feel you could spend have displayed a tad more understanding for those without a formal IT education. You certainly do not find this kind of answers on, say, python dev forums.

I can certainly remember times when this post would have grasped. Even with a gallic English prose:-)
