If a given view has only one ruler associated with it, that ruler should have this flag set. If a given view has more than one ruler (perhaps having one horizontal and one vertical), one of these rulers should be set up as the master ruler. It should have the VRA_MASTER flag set and should have the second ruler's optr in its <CODE>
VRI_slave</CODE>
 field. If there is a third ruler, the second ruler should have its optr in its (the second ruler's) VRI_slave field, and so on. </DD>
