IWBasic
A full-featured 32-bit compiler and IDE — small executables, rich libraries, procedural and OOP styles.
IWBasic is a 32-bit BASIC compiler from Ionic Wind Software with an integrated development environment and syntax similar to classic BASIC.
It creates small, fast Windows programs. The environment is modular — add-on command libraries expand the language. Advanced 2D games and graphics, database*, and 3D games and graphics* libraries are included. Supports both procedural and object-oriented programming.
No external runtime is needed to distribute software you create, and no royalties or fees on anything you ship.
