Welcome to FreeBASIC
Welcome to our world! This page is an overview of our online warehouse of knowledge. Enjoy your surfing and we hope this will be the first of many visits.
Introduction
FreeBASIC is a free, BASIC compiler for Windows (32-bit and 64-bit), 32 bit protected-mode DOS (COFF executables, like DJGPP), and Linux (x86, x86_64, and ARM). It is open source and licensed under the GPL. It is designed to be syntax compatible with QuickBASIC, while expanding on the language and capabilities. It can create programs for MS-Windows, DOS and Linux, and is being ported to other platforms. See About FreeBASIC and Main Features.
Latest Version
FreeBASIC is a beta release compiler and development is ongoing. With each full update, many features are added, and bugs from previous releases are fixed. To see the latest version available, visit the News section on the forum.
Requirements and Installation
Minimum hardware is listed on the Requirements page. Visit our Installation page for setting up FreeBASIC on your computer.
Running
FreeBASIC is a compiler and as such is not packaged with an IDE (Integrated Development Editor), although there are a few IDE's available. For information on using FreeBASIC without an IDE, see Running.
Compatibility with QuickBASIC
FreeBASIC is designed to be syntax compatible with QuickBASIC. For best code-compatibility with QuickBASIC, the QB dialect can be used when compiling source code. See FreeBASIC Dialects and Differences from QB.
Documentation
All official documentation can be found online in the wiki at https://www.freebasic.net/wiki. The online documentation is the most up-to-date resource available. In all cases it can be regarded as the correct version. The downloadable versions of the manual are snapshots of the documentation available at a particular time and should be mostly correct for a specific released version of the compiler. However, we do not maintain multiple versions of the documentation so there may be some discrepancies.
