You could store randRange results in a list and do something like
while ( listFind( randRangeResultList, n ) ) {
n = RandRange( 1, myquery.RecordCount );
}
That in worst case could slow down your app though.
A little more insight into what you want to achieve might help us provide
you with more help.
