| Appeared in | 2025 |
| Memory system | Stack-based |
| Dimensions | Two dimensions |
| Computational class | I don't really know yet |
| Reference implementation | None. This isn't implemented yet |
| Influenced by | Befunge |
Commands
v^<> work like in Befunge
+ adds top two stack values
S subtracts top two stack values, second-from-top first
* multiplies top two stack values
/ divides top two stack values (dividing by 0 raises an error
Don't divide by 0
)
: duplicates top of stack
0-9 push themselves
~ pops the top of stack
# skips the next cell
@ halts
" toggles string mode. AKA pushes everything until another "
. outputs the top of the stack as a number
, outputs the top of the stack as an ASCII character
? goes in a random direction (useful for random number generators...?)
& inputs a number and pushes it
' inputs an ASCII character and pushes it
= Pushes 1 if the top two stack values are the same, pushes 0 otherwise
! pushes 1 if top of stack is 0, otherwise push 0
% modulo
$ swaps top two stack values
{ and } Rotates the stack up and down 3 values respectively
[, ], ( and ) go left, right up and down respectively if top of stack is 0
g gets the top two values on the stack (call them x and y) and pushes the value at (x,y)
p pops x,y,z and writes z to (x,y)
x pops n, duplicates the top n values
- and | are mirrors
j pops x and y, jumps to (x,y)
£ skips the next instruction if the top of the stack isn't 0
l goes to the next e in the pointer's direction if the top value of the stack is 0
e goes back to the last l triggered if the top of the stack isn't 0
r pushes a random number between 0 and 255
m is a NOP, but it is useful (see R)
R goes back to the last m with the current direction
c destroys the stack
