RunR

RunR is an esoteric programming language by User:David.werecat that works in a two dimensional space known as "The Grid".

Instructions

Instruction	Description
S	The start of the program
I	An input generator, when hit it reads a value from the input and stores in the current number
O	An output device, when hit it writes the current number to the output
F	The end of the program
^	A stack action, pushes the current number into the stack
v	A stack action, pops a value from the stack and stores it in the current number
A	A valutory operator, adds the current number and the next value in the stack and stores it in the current number
U	A valutory operator, subtracts the current number and the next value in the stack and stores it in the current number
M	A valutory operator, multiplies the current number and the next value in the stack and stores it in the current number
D	A valutory operator, divides the current number and the next value in the stack and stores it in the current number
0 to 9	Predefinitions, sets the current number to the given value
%	A modular selector, if the current number is zero, sets the current value to true, otherwise sets the current value to false
$	A matrix retriever, it pops a value from the matrix stack and stores it in the current number
&	A matrix signaler, it pushes the current number into the matrix stack
( and )	Focusers, the unconditionally redirect moment to the direction that they are pointing
/ and \	Reflectors
- and |	Walls, when hit from the side no reflection occurs
+	A multidirectional wall, causes a reflection from any direction
#	A conditional gate, when the current value is false, reflection occurs
!	A negatory operator, performs not on the current value
T	A value field, sets the current value to true
@	A conditional jump, when the current value is true, the next instruction is skipped
<	A left turntable, it rotates movement left by 90 degrees
>	A right turntable, it rotates movement right by 90 degrees
~	A rest zone, it causes a brief pause in the program
*	A audial trap, it causes a beep to sound

When the current number goes below 0 or above 255, it simply stops at the high value. Spaces are NOPs. Any other characters results in an error.
