OMNIBASIC

Omnibasic produces small and fast EXE files. Is has a good and intuitive IDE similar to Visualbasic but it is not a RAD (you may not draw forms directly from the working environment, for i.e.). The language structure, the statements and functions are really simple to understand and the documentation is well written and complete.
Its long time Omnibasic is stuck on version 2.2 and no news appear from the site of the developers nor they answer questions or let download the demo version after the free registration process. For this reason here you can grab the last available version.
