BASIC09 is a structured BASIC programming language dialect developed by Microware and Motorola for the then-new Motorola 6809 CPU and released in 1980.
Examples of programs

- Contains: edit, build, BASIC09, dir, del, runb, EXAMPLE1, GFX, INKEY, LIST, FREE in the CMDS directory and OS9DEFS, RBFDEFS, SCFDEFS in the DEFS directory. The BASIC09 floppy disks distributed by Dragon Data had a corrupt RunB file. Fortunately the same file was also present on the OS-9 system disk. The disk has been repaired in this download.

There are several editions of Basic09. The generic was created for 80-column ASCII terminals. The Coco and Dragon editions have short copyright messages in upper case, and send a return to alpha mode code to the screen when <BREAK> is pressed. Choose which one to download and rename it to your liking when installing it in the execution directory.
