X11-Basic is a dialect of the BASIC programming language with graphics capability.
fbxbasic is the framebuffer version of the X11-Basic interpreter. It excecutes BASIC programs, which usually have the extension .bas or .xbas.
The base functionallity is exactly the same as the (normal, X11/X.org version) of X11-Basic. Please also read the man page of xbasic(1).
fbxbasic is independent of the X.org installation and can run without, though supporting all graphics commands of the language.
To show graphics on the screen, fbxbasic trys to open a framebuffer device, supported by the operating system. By default /dev/fb0 is opened, but you can also specify a specific device with the --framebuffer option (see below).
Mouse and keyboard input is also supported by corresponding raw devices which can be specified via the commanline options --mouse and --keyboard .
For detailed help and description of the implemented basic commands take a look at the README file which comes with the X11-Basic package. There is also a full users manual available as *.pdf file on the homepage.
A prompt will be displayed and any command can be typed in. It will be excecuted immediately after pressing return or enter. The input is buffered and can be edited using the up and down arrows on the keyboard.
To quit the program simply enter quit or press CTRL-C.
fbxbasic testme.bas fbxbasic testme.b fbxbasic --framebuffer /dev/fb0 -e 'alert 1,"Hello world !",1," OK ",b'
