Help with Okuma vertical mill 4 axis program codes

Hello guys,

I have an Okuma vertical mill with an OSP200 controller. It has a Koma trunion table added on with the B axis being the 90 degree movement and the A axis being the 360 degree rotation. I use Esprit for programming. Our Esprit has all the 5 axis features enabled but unfortunately the post processor doesn't include the 4 or 5 axis code. My boss wants me to run a part that I can only make in the mill. I would like to use wrap contouring. I believe i could write a small program manually but I not familiar with the codes used for the 4 axis continuous rotation codes. This part is basically a ring with a groove on it. I want to come down with and end mill in a couple of increments while rotating the 4 axis (A) with a controlled feed rate. I know it will be hard to get my hands on a post processor so here is the request. Can someone post a simple G code program for this machine that will do what I explained? I will modify it manually to accommodate my part. Thank you very much in advance.
