Blassic

If you're looking for a software that can run programs written in old Basic interpreters, then Blassic should be on top of your list. This interpreter is designed specifically to execute programs with mandatory line numbers and PEEK & POKE.

One of the best things about Blassic is that it can handle programs written with peculiar control flow constructs or automodifiable code. This means that even if you have some outdated programs lying around, you can still run them smoothly with Blassic.

But what makes Blassic even more versatile is that it can also be used as a scripting language. This opens up a lot of possibilities for users who want to automate certain tasks, without having to learn a new programming language.

For those who are into graphics, Blassic offers graphics modes that are compatible with some classic systems. It also allows users to define their own graphics, giving them greater flexibility in creating their programs.

Overall, Blassic is a great interpreter that is both powerful and versatile. It's perfect for those who are looking to run old programs, as well as for those who want to script or create graphics.
