vector vec1
You cannot directly assign a value to a vector in the symbols section, but vector values can be passed to the variable from a JKL. Use the form: (x/y/z).
Also, you cannot directly compare one vector to another. This example:
if(vector1 == vector2) // then whatever
will not work. You will have to compare each axis of the vectors seperately. With MotS, you have VectorEqual() to solve this inconvenience.
