SmallBASIC is a fast and easy to learn BASIC programming language interpreter ideal for everyday calculations, scripts and prototypes. SmallBASIC includes trigonometric, matrices and algebra functions, a powerful string library, system, and graphic commands along with structured programming syntax.
NOTE: This is *not* "Small Basic" from Microsoft. This is the open source GPL version 3 licensed SmallBASIC originally made for the Palm Pilot and later ported to the Franklin eBookman and Nokia 770 devices.
SmallBASIC works well with "Hacker's Keyboard" available separately.
Some of SmallBASIC's features are:
- SmallBASIC is a multi-platform BASIC language: Currently, Linux, Windows and Android are supported.
- The language is pretty compact: The Debian installer for Linux, for example, comes as a single 340 kb file.
- SmallBASIC features a very comprehensive set of mathematical functions.
- It is an interpreted language with no compilation runs required.
- SmallBASIC supports structured programming, user-defined structures and modularized source files. It is not object-oriented, though.
- It also shows much leeway in questions of syntax: For many commands, there are alternatives, and for many constructs, there are different synonyms available.
- SmallBASIC comes with its own little IDE.
- Graphics primitives (like lines, circles, etc.) are provided, as well as sound and simple GUI functions.
SmallBASIC, which was originally created for the Palm Pilot personal digital assistant in the late 1990's by Nicholas Christopoulos.
