SixtyPical is a very low-level programming language, similar to 6502 assembly, with static analysis through abstract interpretation.

In practice, this means it catches things like

and suchlike. It also provides some convenient operations and abstractions based on common machine-language programming idioms, such as

The reference implementation can execute, analyze, and compile SixtyPical programs to 6502 machine code.

It is a work in progress, currently at the proof-of-concept stage.

The current development version of SixtyPical is 0.8.
