The final product in the QuickBASIC line was '''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 <!--(if ornot all? -->) 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:
