This routine is expected to be called by JMP WM.PANSC(A2) which will be set as the application window control routine. It could also be called by WM.MHIT.
It is not necessary to set the call parameters since they will have been already set by either WM.RPTR or WM.MHIT.
This routine deals with panning, scrolling, splitting and joining.
