Reng

Reng is a two-dimensional programming language that borrows mostly from ><> made by User:Conor O'Brien. While being large on structural and manipulation commands, Reng lacks some basic commands like inequality and exponentiation. One of the most dynamic feature of Reng is the notion of redefining characters.

Language Overview
The program structure is a codebox similar to Befunge and ><>. Reng shares many similarities with ><>, having a near-bijection of commands. Reng focuses more on the algorithmic side of programming, along with the self-modification of the program and of its commands. More control structure is provided, and single-line programming is encouraged.

Commands
Undocumented as of yet.

Interpreters
