PureBasic is a native 32 bit and 64 bit programming language based on established BASIC rules. The key features of PureBasic are portability (Windows, Linux, MacOS X and AmigaOS are currently supported), the production of very fast and highly optimized executables and, of course, the very simple BASIC syntax.
In spite of its beginner-friendly syntax, the possibilities are endless with PureBasic's advanced features such as pointers, structures, procedures, dynamically linked lists and much more. Experienced coders will have no problem gaining access to any of the legal OS structures or API objects and PureBasic even allows inline ASM.
This is not version 0.1 for sure. The up-to-date version is 5.20 LTS, available from the official site. Versin 0.1 was released about 13 years ago, probably even before Mac OS X was released.
