Dead fish +- +.

The title of this article is not correct because of technical limitations. The correct title is actually ><x±∔>.

><x±∔> (Pronounced "Dead fish plus minus plus dot") is a 2D esolang created by User:None1, it is a cross between a cross between Deadfish and ><>, PlusOrMinus and PlusOrOutput, it has a lot of commands that do the same thing.

Commands

><x±∔> adds more commands from ><> and adds all the commands from PlusOrMinus and PlusOrOutput. It also adds the Deadfish command o which becomes O since o is already used.

Commands

The new commands are marked red.

Commands in ><x>

Command	Meaning	Derives from
i	Increments the accumulator	Deadfish
+	Increments the accumulator	PlusOrMinus/PlusOrOutput
-	Outputs the accumulator as ASCII, then decrements the accumulator	PlusOrMinus
.	Outputs the accumulator as ASCII	PlusOrOutput
d	Decrements the accumulator	Deadfish
s	Squares the accumulator	Deadfish
O	Outputs the accmulator as decimal	Deadfish
o	Outputs the accumulator as ASCII	><>
n	Outputs the accmulator as decimal	><>
l	Input a character and store its ASCII code in accumulator	><>
^	IP direction up	><>
v	IP direction down	><>
<	IP direction left	><>
>	IP direction right	><>
#	Skip next instruction	><>
?	If accumulator is zero, skip next instruction	><>
;	Halts the program	><>
space	NOP	><>
0-9	Set the accumulator to the corresponding number	><>
