Syntax

Command	Meaning
I	Increment current cell
D	Decrement current cell
^	Move the cell pointer right
v	Move the cell pointer left
)	Go back to the beginning of the line where the ) is currently at if the current cell is not 0
P	Print a character from the cell's value
N	Print the cell's value
=	Copy the current cell's value to the cell next to it
+	Sum the current cell's value and the cell next to it and put the result to the first cell of the operator and empty the cell next to it
H	Halts program
/	Skips a command if the cell is not zero
↑	Sets the the claw to the cell's value
↓	Sets the cell's value to the claw
G	Goto statement. Halts if the currently pointing cell is negative
;	Gets user input and stores the interger into the currently pointing cell
->	Comment. Ignores all characters until encounters a newline

Move data from a cell to an another cell

= ->Copy from the other cell before erasing the data from it
D)

Using the claw:

↑ ->some value from the other cell
^^^ ->you can move the value basicly anywhere
↓ ->the claw will replace the current cotent of the cell that the pointer is currently pointing at and replcade it with the value from the grabed cell

computational class

HDYFTB is Turing-complete since Brainfuck can be translated into HDYFTB (proof by User:Yayimhere)

[...] -> \n...) yes the \n is a newline
+ -> I
- -> D
> -> ^
< -> v
. -> P

However. Nested loops are literally impossible due to the fact that the starting point of the loop is the beginning of the line (a.k.a. The newline) and is only in one position, and since you cannot backtrack, it's impossible to nest loops

Interpreter

Xyzzy made a python interpreter of HDYFTB. Modified by User: Ractangle.
