That must have been debug.com [0]
Ended up being the right bet though. :)
Did the same thing myself. Struggled for years in Slackware and other builds... had to write my own ADSL driver for broadband to work. Had a dual booting Gateway 2000 PC and always cringed when I selected Linux from the GRUB booter... but it served me very well decades later.
QBasic happened much later, 1991, as part of MS-DOS 5.0. It was considered to be a subset of QuickBasic.
So QuickBasic, as well as it's big brother, Microsoft Basic Professional Development System (which almost no one remembers), was essentially dead by the time QBasic was released.
I only ever used QuickBasic. I still have the manual. Can't make myself part with it.
There was Visual Basic for Windows 1.0 and Visual Basic for MS-DOS 1.0. The UI frameworks were completely different – Windows was GUI, MS-DOS was character mode. The Windows versions continued on until VB6, before being replaced by the very different Visual Basic.NET. Visual Basic for MS-DOS was discontinued after 1.0.
I had it a stack of 3.5" floppies, and the last disk had a bad spot, so some of the framework was impossible to use because I couldn't install it.
That being said, the QuickBasic line and the PDS were amazing -- even the PDS had reams of online documentation on how to use the tooling, straight from the IDE.
I distinctly remember the days my Dad showed me the linker and the library managers. It was like magic: now I could re-use whole chunks of my programs in other programs. Totally world-changing for a little 12 year old kid on an IBM PS/2 Model 50.
