 +  *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.
