Hi David, I know it´s pretty tiresome playing a game in which the other guy doesn´t know the rules. Truth is, I`m just trying to learn from this forum, which I think is very good, excellent. Now, my knowledge of c++ programming is rudimentary. Not a single person was born knowing all about it, and it´s really tough being bombarded with info which I don´t know how to use, yet. Anyway, thanks to all who answered.

Hi Pranit, Thanks a lot. I thence dowloaded the latest version and installed it.

Hi David, Thanks a lot. Yes I threw out the code I was trying compile, and just started anew, using suggestion from just-in-time. I still don´t know if the code actually works, but at least it´s compiled ok. Kindest regards
