RETRO FORTH is a concatenative programming language with roots in Forth. Designed to be compact, learnable, and easy to adapt to specific needs, it has been developed and refined through continual use by a small community over more than a decade. Forth is a stack based programming language created in the late 1960's by Chuck Moore. Over the intervening decades it has evolved through use, with many dialects along the way.

It is a structured, imperative stack-based language with modern facilities including quotations and reflection. It features: - latest version of the RETRO language - a code editor using Markdown subset - literate programming style - code is extracted from fenced blocks in Markdown source allowing easy mixing of code and commentary - allows use of unicode & emoji in source & commentary - interactive listener interface for quick interactions - simple console output and text input - editor provides quick access to numbers and symbols - support for fetching textual data from Gopher servers - file manager - documentation browser It also includes documentation and several optional examples.
