MiLambda

MiLambda(μλ), is esoteric two dimensional turing-complete programming language. In this languages all instructions are letters of Greek alphabet.

Direction control instructions
> Set the direction to right

< Set the direction to left

^ Set the direction to up

v Set the direction to down

Ι Redirect the control flow

ι Redirect the control flow

Сonditional direction control instructions
Z If the cell is not 0, reverse the control flow. (It bounces off the Z)

ζ If the cell is 0, reverse the control flow. (It bounces off the ζ)


 * Reverse the control flow if coming from a right/left-direction

_ Reverse the control flow if coming from a up/down-direction

Υ If store is not equals 0 change direction to left

υ If store is not equals 0 change direction to right

σ If cell is not equals store change direction to up

Σ if cell is not equals store change direction to down

Cell/store control instructions
Δ Increment the cell

δ Decrement the cell

E Adding 10 to current cell value

ε Deleting 10 from value of current cell

ς Set current cell value to 0

Ξ store = cell

ξ cell = store

s memory[cell] = store

g store = memory[cell]

P memory[store] = cell

ρ cell = memory[store]

` Decrement the store

' Increment the store

I/O instructions
Θ Output the cell as character

θ Output the cell as number

π Read character from input

Special instructions
λ halt the program
