I have fond memories of Blitz Basic which still seems to be maintained: https://www.blitzcoder.org/forum/

FreeBASIC https://en.wikipedia.org/wiki/FreeBASIC is a modern, GPL'd compiler that implements nearly all of Microsoft QuickBASIC along with a bunch of extensions. Runs on *nix and Windows.

QuickBASIC was a rather nice BASIC dialect for its era, and you can write well-structured and modular procedural code. Along with a bunch of 2450 GOTO 410 lines, if you really want.

Windows ships with VBScript, it's available via WSH (Windows Scripting Host) and has access to any COM objects you might need.

It isn't a great language but it will go a fair way.

Perhaps, QB64? https://www.qb64.org

There’s also a GUI toolkit with an interface designer being developed for it: https://www.qb64.org/inform/

Small Basic was built to be a good teaching tool: http://www.smallbasic.com/default.aspx

I actually use QBasic in Dosbox. It works and you can find a ton of old tutorials and books.

You can find the MSDos images you need on archive.org.
