Add me to the VB for DOS fan club! I was a user in the mid to late 90s. TurboVision was beyond me at the time (I didn't really know Pascal well at all, and I wasn't good enough at C++), but VB for DOS was just the ticket (mostly) - the language was not terrible, and the form designer was super easy to use. Much easier than me attempting to recreate a nice text UI in C. I wrote a few programs in it.

I do recall the 640 KB barrier being a limitation. I've forgotten the exact details, but, as I recall, the docs implied it shouldn't generally be an issue - but in practice it was. And it'd always be a problem at the most annoying time.

(But it could just have been some large model thing that experienced real mode fiends would instinctively know to avoid? Coming from a 68000 background, for DOS stuff I'd used Borland's huge model or a DOS extender of some kind, to avoid the segmentation one way or another. Maybe that was the problem.)

Despite the occasional problems I had, I always generally liked it, and felt the UIs I created with it looked really rather nice.
