Example:

In the following example, whenever input %I0001 is set, the input bit string %R0001 is rotated 3 bits and the result is placed in %R0002. After execution of this function, the input bit string %R0001 is unchanged. If the same reference is used for IN and Q, a rotation will occur in place.
