Blassic

Blassic is a classic Basic interpreter. The line numbers are mandatory, and it has PEEK & POKE. The main goal is to execute programs written in old interpreters, even those that use peculiar control flow constructs or automodifiable code. However, it can be used as a scripting language, and has some not-so-classic instructions. It has graphics modes that are compatible with some classic systems and user defined.
