QBasic ("QuickBasic") is a language published by Microsoft. The current (and last) version is 4.5, and version 1.1 is distributed with DOS in place of GW-BASIC.
QBasic is extremely easy to use. Its math functions are especially good, and it's a great "learners language" for schools and other similar institutions. It resembles BASIC in its statements, but is more structured -and- flexible at the same time. For instance, line numbers are not required but can be used - as well as "line labels" with text names. The graphics support 256 color 320 x 200 VGA, and 16-color 640x480 VGA, as well as an array of other graphics cards.
QBasic can be expanded with the use of QuickLibraries (.QLB's) which add routines from Assembler and C. It can also be expanded through structured programming - the re-use of SUBroutines and functions. There are many possibilities. Some QLB examples include QBSVGA, a library which gives QB 4.5 SVGA capabilities - up to 1024x768 and 256+ colors, PLUS animation and sprite routines.
You can download QBasic from Microsoft's Web site at this address: http://www.microsoft.com/windows/download/olddos.exe. It comes in a big archive of old MS-DOS utilities.
