QBASIC is a variant of the BASIC programming language. It has no compiler, and the code is executed (interpreted) at runtime in the integrated development environment (IDE). It was released as of MS-DOS 3.0, and was shipped together with MS-DOS 5.0 and higher, including Windows 95. It was soon succeeded by QuickBASIC 4.5, 7.1, and VBDOS 1.0, which included compilers as well as interpreters.
