usage: pin varbptr x y z

PIN specifies which point is to remain fixed during a vector rotation or scaling operation. It acts as like you had stuck a pin at that position and then rotated and/or scaled everything else around that point. VARBPTR is the data variable you wish to PIN. For example,

           pin vecs 0 0 0               ; pin variable VECS at the origin
