QBasic is an old-school, vintage programming language that was designed for beginners. QBasic ran on MS-DOS, and was a more advanced version of BASIC. QB was a lot of people’s first foray into programming (particularly those of us who grew up in the ‘80s and ‘90s). Therefore, a lot of people look back at QBasic with nostalgia.
QBasic is one of the very few programming languages I actually ever even used – back when i was a very young kid – so I do have some faint nostalgia for it. Great to see such a dedicated community keeping it alive.
