HASSL (Hexadecimal, ASCII, Symbolic, and Stack-Based Language) is a stack-based esoteric programming language created in 2023 by Ethan T. Stanger.

Language summary

HASSL programs begin by defining a number of states. These states can be any of the single hexadecimal digits (0-9, A-F), and can be written anywhere in the program. Execution starts with the first 0 found in the program, and from there on commands are run one character at a time.
