Discontinued Microsoft BASICs

QBasic is an integrated development environment (IDE) and interpreter for a variety of dialects of BASIC which are based on the QuickBASIC compiler and the QuickBASIC Interpreter. Code entered into the IDE is an intermediate representation (IR), and this IR is immediately executed on demand within the IDE.

GW-BASIC is a dialect of the BASIC programming language developed by Microsoft from IBM BASICA. Functionally identical to BASICA, its BASIC interpreter is a fully self-contained executable and does not need the Cassette BASIC ROM found in the original. It was bundled with MS-DOS operating systems on IBM PC–compatibles by Microsoft.

Microsoft QuickBASIC (also QB) is an Integrated Development Environment (or IDE) and compiler for the BASIC programming language that was developed by Microsoft. QuickBASIC runs mainly on MS-DOS, though there was also a short-lived version for Classic Mac OS. It is loosely based on GW-BASIC but adds user-defined types, improved programming structures, better graphics and disk support and a compiler in addition to the interpreter. Microsoft marketed QuickBASIC as the introductory level for their BASIC Professional Development System. Microsoft marketed two other similar IDEs for C and Pascal,

BASIC programming language implementation for Amiga computers

MBASIC is the Microsoft BASIC implementation of BASIC for the CP/M operating system. MBASIC is a descendant of the original Altair BASIC interpreters that were among Microsoft's first products. MBASIC was one of the two versions of BASIC bundled with the Osborne 1 computer. The name "MBASIC" is derived from the disk file name MBASIC.COM of the BASIC interpreter. MBASIC, like its predecessor family of 8-bit interpreters Microsoft BASIC, were heavily inspired by Digital Equipment Corporation PDP-10's BASIC-PLUS.
