I find it interesting that QBASIC is mentioned for several reasons:
1. This language and any of its predacessors are hardly used these days. And, if they are, it's most likely for nostalgic reasons. At one time, I remember, some schools used it for introductory programming courses. For a time, in the mid 90s, some nostalgic frenzy seemed to have spiked (I remember messing around with BasicA on a Commodore 64 and I'm sure others were having fun with it on Apple 2s) its usage; Gorillas (wassit?) was a fun game. But, certainly, it's no more widely used now (if used as much) as languages like Pascal and certainly not C, C++, Java, C#, etc. I remember finding it quite novel in Windows 3.1 Workstation, ten years ago. Are people still actively developing in QBASIC?
2. The similarities between QBASIC and Visual Basic are nominal at best. Does .NET even support QBASIC? Hell, does Windows XP even come with QBASIC installed? (I'm a Linux-only user)
3. Is there anything useful about QBASIC that warrants its use over another language? Or even a reason to dedicate a topic to it? Some calculators use a BASIC interpretor still... perhaps that?
Sorry, I had to break from the work I was doing and eat my jello and drink my coffee (I know, it's weird).
