With MS-DOS 5.0 in 1991, QBasic replaced the older GW-Basic/Basica as the standard BASIC interpreter for the PC. It was essentially a subset of the QuickBASIC 4.5, an IDE that Microsoft released in 1988. The first version of QuickBASIC goes back to 1985.
Compared with its predecessor, QBasic offered better support for structured programming (subroutines) and dropped the line numbers. QBasic was part of all Microsoft operating systems at least up to Windows 98, where you will find it on the CD in a folder labeled OLDMSDOS.
Below you will find a few essential links, and some games that are either distributed as QBasic modules, or compiled but with the source code included.
