This is a newer programming language that is great for making games and other software on the Atari 8-bit. It compiles to concise machine language and only the module sections that you use. I did a few tests, and the executables run faster than compiled Turbo Basic XL. You can set it up with things like fast graphics, fast math, etc. It runs from PC DOS, compiles down to assembly. Then you use MADS Assembler to build your final binary. You can make an XEX or Cartridge ROM file from there.
