Such things were also my start into programming (after finding and reading the GWBASIC manual twice). Later followed by Turbo Pascal, Visual Basic and much later by many other languages.
I've been wondering recently what the equivalent for today's kids would be (my children aren't that old yet, but the day will likely come). In terms of ubiquity and being able to immediately start, JavaScript would come close, but it's orders of magnitude more complex in my eyes. Perhaps things like Scratch or SmallBasic for trying out things on their own. But these days we also have ubiquitous documentation, tutorials and other things on the web, so basically everything is a lot more approachable than decades ago ...
