Welcome to the Befunge page! Here, you'll find a description of the language as well as a list of sample programs in that language.

Befunge is a programming language with some very unusual standards, as a two-dimensional, self-modifying, stack-based programming language. Apparently, it was designed in 1993 by Chris Pressey, merely to be as difficult to compile as possible.
All operations in Befunge are limited to a single character, and the
source text can be traversed in any direction through the file. The
"Instruction Pointer" starts in the upper left corner and proceeds
to the right, running every character it crosses. When it reaches
< > ^ v, that pointer will turn and travel in the new
Instead of variables, all operations act on one global stack of
integers, similar to Forth. 0-9 will just push their value,
+ - * / % pop the top two values and push their normal result,
. prints out the top number, and
, prints the corresponding
