:	Get input from the user and push it.
{	Pop a off the Document. If a is 0, rotate IP direction left (counterclockwise) 90°.
}	Pop a off the Document. If a is 0, rotate IP direction right (clockwise) 90°.
+ - * / %	Addition, Subtraction, Multiplication, Division, Modulo. Pop a and b off the Document, then do b <operator> a and push the result to the Document.
