SelectedRowIndex is int
SelectedRowIndex = ListSelect(LIST_List1, 1)
WHILE SelectedRowIndex <> -1
Trace("Row #" + SelectedRowIndex + " is selected")
i++
SelectedRowIndex = ListSelect(LIST_List1, i)
END
 
// Equivalent to:
// FOR EACH SELECTED ROW OF LIST_List1
// Trace("Row #" + LIST_List1 + " is selected")
