visual basic started like QBasic?

I still use QBASIC, QB, and VBDOS under Windows 7, 64-bit. But ... I had to install Microsoft's VM and then install Microsoft's 32-bit XP to run underneath it. Microsoft's 32-bit operating systems still support 16-bit applications and still support a kind of hobbled, but still useful, DOS emulation (using CMD.) The 64-bit O/S hosts the 32-bit O/S which then still supports the DOS emulation. So that's one way to go. If you have Win7 Professional or above, Microsoft gives you XP free. (Or they did a year ago when I last checked.)

I haven't tried installing a 32-bit Win7. But I would expect it to run QBASIC under the CMD prompt, since I believe 32-bit Win7 still supports 16-bit code execution. I think it is just the 64-bit variety where they decided to "oh, screw it" regarding trying to retain support for 16-bit TSS (task state segments.)

I believe there are non-Microsoft DOS emulators around, though. Free and decent, from what I've occasionally read.

Windows XP 64-bit, Windows Vista, Windows 7, 8, 8.1, Linux and MacOS do not include DOS.

why don't you use dosbox.

we use dosbox emulator to train students turboc/turboc ++ which are dos based.
