QB64

If you used to develop programs in Quick Basic or Qbasic, you probably understand that your projects might have a little trouble running on newer versions of Windows.
QB64 is a software solution that enables you to create compatible programs or turn existing ones into versions that are compatible with Windows XP, Vista and newer.

Understanding QB64

This application is actually a modern alternative to the Basic programming language that is both a BASIC compatible editor and a C++ compiler. It can create working executables from programs that were created with Qbasic or Quick Basic 4.5, making them compatible with 32 or 64 bit Windows computers.
It provides you with several handy features, including the ability to play music or sound files, stereo sound, TCP/IP Internet communication, email messages and improved graphics. You can access a set of example programs from the application's "programs" folder so that you can study the app's capabilities before creating your own content.

DOS-inspired interface

QB64 comes with a DOS-inspired interface that packs intuitive functions, available in its traditional menus. Unlike other applications with DOS interfaces, this one lets you use your mouse in order to select content or interact with menus or buttons.
It also packs a comprehensive help that can help you understand its functions and operate them with ease. Given that this program was designed to help users generate compatible executables out of Qbasic BAS files, you need medium-to-advanced PC skills or at least previous experience with similar software to benefit from its full array of functions.

Portable tool

Given that this application is portable, you don't need to install it on the target computer. Simply unpacking its contents and launching the executable grants you total access to its controls. However, since it packs a lot of files, the decompressing process might take a while.
Furthermore, it won't create any additional files or folders on your computer without your explicit permission, nor will it tamper with any of your Windows registry entries.

Reliable app that creates working executables of Qbasic BAS files

All things considered, if you're looking for an efficient way to make programs created with Quick Basic 4.5 or Qbasic compatible with newer versions of Windows (XP and newer), QB64 might just be what you're looking for. It packs a wide variety of functions, comes with a handy help manual and requires no installation.
