You should be able to create arrays bigger than that, limited only by the memory available on your computer. You might not be able to create such large arrays on the stack, or as a global variable, but you could create it on the heap: char* array = new char[10000*10000]; Or a better way to do that might be: #include <array> #include <memory> using array_type = std::array<char, 10000*10000>; auto array = std::make_unique<array_type>(); > I have > the computer fill an array with the fractal data for colors, and then it > writes a bitmap file with the data and I can access that through BASIC or > just show it to a friend.

That means you're already using GCC. > I also need to knowk, please, how and where to download GCC, the > latest version. I'm not finding info on that. As explained at https://gcc.gnu.org/install/binaries.html the GCC project does not provide binaries to download, we only provide source code. There are third-party binaries available, and the mingw and mingw-w64 ports of GCC for MS Windows are available from their respective projects. The https://gcc.gnu.org/install/binaries.html page has links to them, and there are other builds of them available like http://tdm-gcc.tdragon.net/ > In addition, when I run the > dev-c++ programs from bASIC, a window comes up on the screen saying so.
