The Howdy Glossary

IBM Advanced BASIC was an extension of the BASIC programming language developed by IBM as part of their Operating System/2 (OS/2) operating system. The language included support for object-oriented programming and other advanced features that were not available in earlier versions of BASIC. Advanced BASIC was designed primarily for use in developing graphical user interface (GUI) applications on OS/2, and it integrated closely with the Presentation Manager environment used by OS/2 programs at the time. However, the popularity of Advanced BASIC diminished over time along with OS/2's decline in relevance compared to Windows-based platforms during the 1990s.
