Return type: LOGICAL
Applies to: BROWSE widget
The AVM maintains a numbered list of selected rows, starting at 1. When the SCROLL-TO-SELECTED-ROW( n ) method is encountered, the AVM searches this list to find the nth selected row. If the row is successfully scrolled into view (or if the scroll is unnecessary), the method returns TRUE.
