Is Brainfuck extension with new commands. All commands are single symbol without parameters.
| Character | Name | Meaning |
|---|---|---|
| Base | ||
>
|
RIGHT | Increment the pointer (to point to the next cell to the right). |
<
|
LEFT | Decrement the pointer (to point to the next cell to the left). |
+
|
INC | Increment (increase by one) the byte at the pointer. |
-
|
DEC | Decrement (decrease by one) the byte at the pointer. |
.
|
OUT | Output the value of the byte at the pointer. |
,
|
IN | Accept one byte of input, storing its value in the byte at the pointer. |
[
|
JUMPZ | Jump forward to the command after the corresponding ] if the byte at the pointer is zero.
|
]
|
JUMPNZ | Jump back to the command after the corresponding [ if the byte at the pointer is nonzero.
|

SHR | Performs a single right logical shift of the byte at the pointer. |
{
|
SHL | Performs a single left logical shift of the byte at the pointer. |
~
|
NOT | Performs a bitwise NOT operation on the byte at the pointer (all 1's and 0's are swapped). |
^
|
XOR | Performs a bitwise XOR operation on the byte at the pointer and the byte in storage, storing its result in the byte at the pointer. |
&
|
AND | Performs a bitwise AND operation on the byte at the pointer and the byte in storage, storing its result in the byte at the pointer. |
|
|
OR | Performs a bitwise OR operation on the byte at the pointer and the byte in storage, storing its result in the byte at the pointer. |
