Deadbird

Deadbird is a Deadfish derivate by User:ChuckEsoteric08

Additions

Instead of having a single accumulator, Deadbird has 4 accumulators. It adds following commands to Deadfish:

n - moves to the next accumulator, wrapping
c - outputs as a character
g - inputs a character
z - sets accumulator to zero
f - skip next command if accumulator is zero
(x/y) - define function x (can be only a single character) as y. Allows recursion
