What is Liberty BASIC?
Liberty BASIC is a Windows programming environment for writing utilities, games and other desktop applications in BASIC. It combines a code editor, compiler and debugger with the FreeForm tool, which lets you draw windows and generate their interface code. An interactive tutorial and included examples provide starting points for learning the language.
Programs can use graphical controls, graphics, sound, serial communications and Windows API calls. The debugger supports stepping through code, inspecting variables and setting breakpoints. Liberty BASIC compiles to an intermediate format executed by its runtime engine rather than directly to native machine code.
The trial lets you explore the environment, but creating standalone applications with the runtime requires a purchased license. The publisher's historical FAQ identifies version 4.5.1, and its download page links to lb451setup.exe. Its detailed compatibility guidance lists Windows 7, 8, 8.1 and 10; Windows 11 compatibility has not been established here. The screenshot is the publisher's older v4.0 editor on Windows XP, not a capture of the 4.5.1 package.
