ScriptBasic is an interpreter for the old language BASIC. It runs on Win32 as well as on UNIXes as a command-line or CGI program interpreter. It includes an interpreter, a compilable, well-documented embedding and extending interface for the C programmer, and a rich set of commands and functions.
GNU/Liberty Basic Compiler Collection (GLBCC) is a suite of tools that allow Liberty Basic source code to be compiled directly to executable programs. It leverages greatly off of the GNU Compiler Collection, which allows it to run both on Windows and Linux, while also having the ability to generate both Linux and Windows executables on Linux via the Mingw cross compiler. The suite also includes a frontend program that has both a GUI and CLI to provide a simple environment to compile Liberty Basic code.
Lemick is a programming language similar to traditional Basic implementations but with all the attributes of the modern programming tool. Major design features include a source to bytecode compiler and bytecode to object code compiler, platform-independence of the compiled code (through the use of VM bytecode), native support of concurrent and distributed programming (multi- threading and distributed multi-threading), rendezvous for message passing, replicas and ultra-weak consistency model for shared memory simulation, advanced exception handling mechanism including distributed version, weak typing, mixed style of procedural and object-oriented programming (relaxed OO), and high performance.
Ccide reads C, C++, BASIC, or bash source code containing embedded decision tables from stdin, expands the tables, copies the remaining statements, and forms a compilable C or C++ source module, executable bash script, or interpretable BASIC program. Erratic side effects are avoided by evaluating all condition expressions at exactly the same time, and by performing all evaluations and actions in the original sequence.
The Amsterdam Compiler Kit is a fully-featured retargetable compiler toolchain. It will cross-compile ANSI C, K&R C, Pascal, Modula-2, Occam, Fortran and Basic for a number of architectures including, but not limited to, the 6500, 68000, Z80, i80, i86, i386, and PDP-11. It provides a complete development environment including preprocessors, compilers, assemblers, linkers, librarian tools, and target download tools.
FreeBASIC is a self-hosting 32-bit BASIC compiler. It makes use of the GNU binutils programming tools and can produce console and GUI executables, and dynamic and static libraries. It fully supports the use of C libraries and has partial C++ library support. It supports a C style preprocessor that is capable of multi-line macros, conditional compilation, and file inclusion. When used in its "QB" language mode, it provides a high level of support for programs written for QuickBASIC.
