Greed

GREED is an esoteric programming language made by las_r with only 6 commands. It uses a stack tape made of single-bit values and also has a separate memory for storing 1 bit.

It's heavily inspired by Brainfuck. However, it has many differences, especially in the loop behavior.

An interpreter can be found here.

• STK: Stack tape
• PTR: Stack pointer
