ENDDATA =================================== and I would like to find where the grid point definitions start(marked with $ sign) after that I will take the coordinates into vectors(hopefully). I guess STL could help me and this way I would also improve my STL knowledge. I just wanted some advice before start coding this.

I guess STL could help me and this way I would also improve my STL knowledge. I just wanted some advice before start coding this. Use 'std::string' and 'std::ifstream' and 'std::getline'. Get a book on the Standard library, or just study the manual on those three elements of the library. You're bound to arrive at a solution if you know what you want.
