X11-Basic is a dialect of the BASIC programming language with graphics capability. It has a very rich command set, though it is still easy to learn. The syntax is most similar to GFA-Basic for ATARI-ST. It is a structured dialect with no line numbers. A full manual and command reference is available.
GFA-programs should run with only a few changes. Also DOS/QBASIC programmers will feel comfortable.
This implementation is one of the fastest basic interpreters for Android. Programs can be compiled into a platform independant bytecode.
You can directly type in commands and formulas, which are beeing evaluated. This way the interpreter works also as a pocket calculator.
Launcher shortcuts can be placed on the desktop to directly excecute BASIC programs.
Basic programs can be written with any (third party) text editor.
The BASIC programs must be placed into the bas folder (/mnt/sdcard/bas). You can find many more example programs on the X11-Basic homepage: http://x11-basic.sourceforge
