The information Bob and Nadya have provided will do the job, but if you want to look at details on the Groupwise object model try http://developer.novell.com/ndk/gw-index.htm. You'll need to set up an account (free) before you can download the stuff. Groupwise Objects API Objects details things, and there is a section on the constants used. It was not real easy to use, but you might find it worth the pain.
