Help with new Haas & program format

We just got a new VF-5ss up and running.Haas programs apparently use "I,J,K" as incremental for center point in G2-G3.
All of our programs (hundreds!) are from cincinnati's and use I,J,K's as absolute positions. Is there a paramiter to change in
the VF-5 to make it read absolute position with G2/G3???:confused:

Thanks
