'''QuickBASIC''' is a [[BASIC]] compiler/interpreter for DOS and OS/2. It should not be confused with [[QBasic]], which is an interpreter-only version of QuickBASIC 4.5 with a reduced instruction set. An [[IDE]] has been included with QuickBasic since version 2.0.

'''QuickBASIC Extended 7.1''' (also called '''Microsoft BASIC Professional Development System 7.1''' or '''QBX'''~~) was the final product in the QuickBASIC line~~. (According to [[wp:QuickBASIC|Wikipedia's QuickBASIC entry]], the QBX IDE did not run under OS/2.)

Microsoft eventually replaced QuickBASIC with [[Visual Basic]]. (Visual Basic 1 for DOS can compile most ~~~~ QB code unchanged.)

==QBasic==

QBasic is an interpreter that [[Microsoft]] distributed with later versions of [[MS-DOS]]. It is based on QuickBASIC 4.5, with parts of the language and the [[compiler]] removed. Any program specifically written for QBasic will work under QuickBASIC 4.5 or later without changes.

=="Standard"==

The QuickBASIC language has become something of a de facto standard, inspiring several later compilers, many of which attempt to be QB-compatible (with varying degrees of success). A few of the modern compilers include:
