Basic09
From the Basic09 manual: Basic09 is an enhanced structured BASIC language programming system specially created for the 6809 Advanced Microprocessor. In addition to the standard BASIC language statements and functions, Basic09 includes many of the most useful elements of the Pascal programming language so that programs can be modular, well-structured, and use sophisticated data structures. It also permits full access to almost all of the OS-9 Operating System commands and functions so it can be used as a systems programming language. These features make Basic09 an ideal language for many applications: scientific, business, industrial control, education and more.
Basic09 is unusual in that it is an Interactive Compiler that has the best of both kinds of language system: it gives the fast execution speed typical of compiler languages plus the ease of use and memory space efficiency typical of interpreter languages. Basic09 is truly a complete programming system that includes a powerful text editor, multi-pass compiler, run-time interpreter, high-level interactive debugger, and a system executive. Each of these components was carefully integrated so the user "sees" a friendly, highly interactive programming resource that provides all the tools and helpful "extra" facilities needed for fast, accurate creation and testing of structured programs.
