Schemy Lisp En DOS
Summary
SLED is a Scheme-like Lisp interpreter for DOS/DOSBox. The article details its design, features, and usage, including immutability of core symbols, tail-call optimization, and a compact C89 codebase (~1.1K lines). It also covers data representations (symbols, atoms, closures), S-expressions, builtins, and system constraints of a DOS environment.
