PowerBASIC

'''PowerBASIC''' is a small family of compilers for DOS and Windows by PowerBASIC, Inc. Its main selling point is the efficiency of the compiler and its ease of use. (The "easy" part is debatable; working with windows is not as easy as Visual Basic, but then, almost nothing is.) For a brief history of PowerBASIC, read its Wikipedia entry.

Code example

Many of the BASIC examples listed on Rosetta Code will work unchanged in PowerBASIC -- especially the DOS version -- although there are often enough differences between PB and the various other BASICs (especially the Windows versions) to warrant PB-specific examples.
