QuickBasic Compiler and Visual Basic for DOS

All offered Compilers at a Glance

The most popular Compiler - QuickBASIC 4.5

This version is very appreciated by game developers in particular, but not exclusively. For this purpose, a great number of extensions (program libraries) are available. Both the english and german version are ready for download below.

The final QuickBASIC Version - BASIC Professional Development System 7.1

This version is also known as QuickBASIC Extended, in short: QBX. Finally, the command set was significantly enhanced, primarily in the field of databases usage. Therefore, QBX is particularly suitable for application development which has huge amounts of data to process.
Below are two download packages available: First, the untouched version, formerly distributed on eight 3½″ floppy disks with a maximum of 1.44 MB each. Second, the uncompressed version, which can be used immediately without installation.

The Next Generation - Visual Basic for MS-DOS

Microsoft launched Visual Basic 1 (short: VB), which replaces QuickBASIC. This version is available for both OSs MS-DOS and Windows. After that, Microsoft terminated developing DOS-based software development environments.
There are again two download offers below: The untouched version, formerly distributed on seven floppies and the uncompressed portable bundle for instant usage.
