FreeBASIC is a free/open source (GPL), BASIC compiler. When used in its "QB" language mode, FreeBASIC provides a high level of support for programs written for QuickBASIC. Many programs written for QuickBASIC will compile and run in this mode with no changes needed. However, for compilation in the FreeBASIC default language mode, most substantial programs will require changes. FreeBASIC is a high-level programming language supporting procedural, object-orientated and meta-programming paradigms, with a syntax compatible to Microsoft QuickBASIC. In fact, the FreeBASIC project originally began as an attempt to create a code-compatible, free alternative to Microsoft QuickBASIC, but it has since grown into a powerful development tool. FreeBASIC can be seen to extend the capabilities of Microsoft QuickBASIC in a number of ways, supporting more data types, language constructs, programming styles, and modern platforms and APIs. Compile programs withfbc.bin -p /boot/system/develop/lib -prefix /boot/system/ -l root file.bas or use the included script:fbc file.bas Compiled for Haiku by coolcoder613 Adapted and packaged for Haiku by Michel Clasquin-Johnson.
