Using the Hook
This hook is a very simple, but very useful one. It's triggered before the system monitor calls cxRedisp for any context. Both the A and B registers will contain the current context (basically the value of cxCurApp.) Returning with the zero flag set will cause the cxRedisp vector to be called; returning with it reset will prevent the vector from being called (this will generally break any system context!)
