Line 1: {{language\|QuickBASIC \|exec=compiled \|strength= \|safety= \|express= \|checking= \|gc= \|site= }}{{language programming paradigm\|Procedural}} {{implementation\|BASIC}}{{IDE}}{{Compiler}} '''QuickBASIC''' is a [[:Category:BASIC\|BASIC]] compiler/interpreter for [[DOS]] and [[OS/2]], produced by [[Microsoft]] from 1985 through 1990. An [[:Category:Integrated Development Environments\|IDE]] has been included with QuickBASIC since version 2.0. Line 4 ⟶ 14: The final product in the QuickBASIC line was '''QuickBASIC Extended 7.1''', also called '''Microsoft BASIC Professional Development System 7.1''' or '''QBX'''. (According to [[wp:QuickBASIC\|Wikipedia's QuickBASIC entry]], the QBX IDE did not run under OS/2.) QuickBASIC was succeeded in 1991 by [[:Category:Visual Basic\|Visual Basic]]. Despite being sold as part of the VB line of products, '''Visual Basic for DOS''' ('''VBDOS''') is actually a QuickBASIC compiler and can compile most (if not all) QB code unchanged. (It might help to think of VBDOS as "QuickBASIC plus [[wp:Text-based user interface#~~TUI~~Under ~~under MS-~~DOS and Microsoft Windows\|character windows]]".) It should be noted that while QuickBASIC is not 100% compatible with [[BASICA]] and [[:Category:GW-BASIC\|GW-BASIC]] (the interpreters included with older versions of DOS), ''most'' BASICA/GW-BASIC commands work identically. (If a program is marked as working with GW-BASIC, there is a strong chance that it will work in QuickBASIC. The QuickBASIC help file includes a side-by-side comparison of incompatible features of the languages.) Line 14 ⟶ 24: ==QBasic== QBasic is an interpreter that Microsoft distributed with later versions of MS-DOS, replacing the classic-style interpreter (GW-BASIC) that was included with earlier versions. It is based on QuickBASIC 4.5, with the [[compiler]] and parts of the language removed. ~~Any~~''Almost'' any program specifically written for QBasic will work under QuickBASIC 4.5 or later without changes. (Note that it is not correct to refer to QuickBASIC as QBasic -- Microsoft considers them to be two separate products.)
