portable, fast, lightweight BASIC interpreter
BScript is a (yet another) BASIC interpreter. It is free software and open-sourced, licensed under the terms of the GNU General Public License version 2 or later. You can use BScript to teach BASIC to your students, write understandable shell scripts (good bye, spaghetti code!), automate simple tasks, or even write a game!
The following BASIC code will be executed by BScript without problem:
print "Hello, world!"
Documentation for BScript isn't yet available. However, it's so simple that you can use this webpage for reference. The following might also be helpful:
Subdirectory examples/ in the source-code tarball contains many interesting examples which you might want to try.
BScript is always available from http://sourceforge.net/projects/bscript/. The latest stable version is 0.3, you can download it as bscript-0.3.tar.gz.
BScript only comes in source-code. In order to compile and install it on your system, unpack the source-code tarball and simply execute the following commands:
./configure make make install
Note: you need lex and yacc to compile BScript. However, flex and bison would be fine replacements.
BScript can be compiled on Linux, other Unices, and Microsoft Windows.
If you want to use the development version of BScript, checkout the source using anonymous CVS (when asked for password, just press Enter), so something like this:
cvs -d:pserver:anonymous@cvs.sourceforge.net:/cvsroot/bscript co bscript

As for the time being, development of BScript is suspended due to my limited time. If anyone is interested in taking over the maintainance of BScript (as well as further development tasks), please contact me at ariya@kde.org.
To be able to run at reasonable speed, BScript parses the BASIC code into sort-of p-code which will be executed by a virtual machine. Bear in mind that BScript was born when I learned lex, yacc, and virtual machine at first time and therefore might have inherent design mistakes.
