Axo

axo is a language inspired by Befunge, invented by Jannis Harder in 2004. "axo" is pronounced like the German words "ach so".

The Axo interpreter has three modes which has slightly different operation. It uses an unlimited stack, and 2048 memory cells of 32 bit signed integers. Popping from an empty stack produces zero (0).

Raw mode
Any other character pushes its ASCII value.

String mode
Any other character pushes its ASCII value.
