FutureBASIC is an integrated development environment for macOS used to create software for Macintosh and Windows. The programming language allows developers to create 32-bit and 64-bit applications using a basic syntax that is easy for newcomers to learn yet powerful enough for experienced programmers. FutureBASIC can work with both console-mode text applications and graphical interfaces, making it versatile for different types of projects. It provides access to operating system functions through built-in commands or by calling external C/C++ libraries. The environment offers features such as code folding, color-coded syntax checking, debugging tools, vector drawing in the GUI toolkit's language extension module (LEM), string handling options, and support for multi-threading.
