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.
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.
