I may be wrong, but I believe what makes it difficult is that the Help file assumes some linear model statistics that you may not have. I suggest that you look for a tutorial on linear models first and then re-read the Help. Incidentally, the provenance of the syntax is GLIM (correction requested if I'm wrong), and the Nelder-McCullough book on GLM's has a chapter on linear models and syntax that is relevant, iirc.
