ASCIInyelv

ASCIInyelv is a fictional or esoteric programming language designed to express programs entirely with ASCII characters. The name combines ASCII and nyelv, the Hungarian word for language, signaling its constraint to plain-text symbols and its use in discussions of language design. It is commonly described in educational and hobbyist contexts to illustrate how simple textual syntax can encode computation and control flow without relying on extended character sets.

ASCIInyelv typically uses a small, closed set of ASCII tokens and a stack-oriented execution model. Core operations include PUSH, POP, arithmetic commands such as ADD, SUB, MUL, DIV, and I/O commands like PRINT and INPUT. Statements are separated by whitespace or line breaks, and programs are viewed as a sequence of lines. A minimal program to compute 5 plus 3 and output the result might push 5, push 3, add, then print.

Because ASCIInyelv is not standardized, there are no official specifications or reference implementations. It functions mainly as an educational tool and as a sandbox for experimenting with tokenization, parsing, and interpreter design. Hobby projects and lightweight interpreters exist in online repositories, often serving as demonstrations of design choices for ASCII-only languages.

Status: ASCIInyelv remains largely a conceptual or teaching-oriented construct rather than a practical programming language. It has no widely adopted syntax or runtime and is discussed primarily in forums and coursework on language design and esoteric programming languages.
