SDOTOS

SDOTOS is an esoteric programming language created by User:Infinitehexagon.
Feel free to try to find the computational class of this language and make an implementation or an interpreter
SDOTOS has 16 commands, and 8 built in instructions.

Commands

Hexagon

Command	Description
i	Increment by the character next to it. If the character next to it is not a number 0-9, then increment the hexagon variable by the ASCII value of the next character.
n	Decrement by the character next to it. If the character next to it is a non-number value, then increment the hexagon variable by the ASCII value of the next character.
f	output the Hexagon variable as an ASCII character.
t	multiply the Hexagon variable by the Stopwatch variable and save the result into Hexagon variable
e n	go to line n if the Hexagon variable is non-zero.
h["name"] (commands)	begin a definition for a function
x	reverse the value in the Hexagon variable then store it into the Stopwatch variable.
g	end a definition for a function (Both variables)

Stopwatch

Command	Description
s	increment the Stopwatch variable by 1
o	output the Stopwatch variable as an ASCII character.
p	set the Stopwatch variable to 0
w	double the value of the Stopwatch variable
a	Add the value of the Stopwatch variable to the Hexagon variable and store it into the Stopwatch variable.
c	store the Stopwatch variable's value into the Hexagon variable's value.
!	output the Stopwatch variable as a plain value
m	decrement the Stopwatch variable by 1

Built-In Commands and Operators

Both

Command	Description
\	output both variables as an ASCII character
?	divide both variables by 2
%	get the modulo of the Hexagon variable to the Stopwatch variable and store it into Stopwatch variable
#	skip the next command if one of both variables contain 0.
u	get input for hexagon variable
~	get input for stopwatch variable
:	if the character next to it equals the Stopwatch variable as an ASCII character, then do the next command, but if not,skip to the next ":".
E	loop to the line above it is either one of the variables is a non-zero value.
>["name"](value)	create a new variable with the name and a value, and if the variable already exists then set it to a value

Keep in mind that already defined functions have to be marked in brackets so that you can call up functions.

Example Programs

Hello World program

iHfptiefptilofpiiofpti,fpti fptiWfptiofptirfptilfptidfpti!fpt 
//the "pt"s are used to set Stopwatch to 0, then multiply Hexagon by Stopwatch to set Hexagon variable to 0.

Truth-machine

h[$]ptg     //define a function named "$" and set the Hexagon variable to 0 
u#[$]        //check if hexagon is 0 from input and if so set both variables to 0
f          //output hexagon
e 3        //goto line 3
