The **Sort **property is a reference to a structure containing all the sort information for this BrowseClass object. The BrowseClass methods use this property to implement multiple sort orders, range limits, filters, and locators for a single browse list.

**Implementation: **The BrowseClass.Sort property mimics or shadows the inherited ViewManager.Order property. The Sort property is a reference to a QUEUE declared in ABBROWSE.INC as follows:

**BrowseSortOrder QUEUE(SortOrder),TYPE !browse sort information**

**Locator     &LocatorControl    !locator for this sort order**

**Resets      &FieldPairsClass   !reset fields for this sort order**

**Thumb       &ThumbClass        !ThumbClass for this sort order**

**                END**

Notice this BrowseSortOrder queue contains all the fields in the SortOrder queue declared in ABFILE.INC as follows:

**SortOrder    QUEUE,TYPE        !VIEW sort information**

**Filter        &FilterQueue     !ANDed filter expressions**

**FreeElement   ANY              !The Free key element**

**LimitType     BYTE             !Range limit type flag**

**MainKey       &KEY             !The KEY**

**Order         &STRING          !ORDER expression (equal to KEY)**

**RangeList     &FieldPairsClass !fields in the range limit**

**             END**

And the SortOrder queue contains a reference to the FilterQueue declared in ABFILE.INC as follows:

**FilterQueue QUEUE,TYPE   !VIEW filter information**

**ID           STRING(30)  !filter ID**

**Filter       &STRING     !filter expression**

**            END**

So, the BrowseSortOrder queue is, among other things, a queue of queues.

The AddSortOrder method defines sort orders for the browse. The SetSort method applies or activates a sort order for the browse. Only one sort order is active at a time.
