If your evaluation of the free trial version is positive, why not buy that shareware version?
And what happens if you use QBasic yourself (as programmer) in a DOS-box, but compile to an exe (see http://qbnz.com/pages/faq/ ), then run the exe by doubleclicking in Explorer or via a pif-file. Those 2 methods will implicitely make a DOS-box, of course, but well, the program has to run in some window and that can't be a Windows window, so it has to be a DOS-window. But nobody will mind, because, in fact, it IS a DOS-program, not a program with a GUI (like you make with Visual Basic). And that seems to be what you want.
Hope this helps.
Is there any way to download a version of QBasic for Windows for free? I don't want Visual Basic. I want something that will be compatible with directly transfered code from the DOS version of QBasic but will work on Windows XP without needing to use DOSBox. I've found something online called Liberty Basic, but it's shareware and only offers a free trial version.
