Hi Eliot, Thanks for the help.
No pressure. I only want help from those who are willing to help. Those who are NOT interested may kindly ignore my messages. There is no obligation at all. The issues I highlighted have been a recurring problem on Google. So, there is a recurring pattern emerging and perhaps this thread could solve it once and for all. As for what I am using it for, I am trying to complete a book called Modern C. I wish to finish it. Thank you.

But I think you're reaching the limit of the handholding the community may be prepared to offer ... Also, you never said what you're *really* trying to accomplish.
