usOrderNum |
Order number to retrieve index handle for. |
This function returns the index handle corresponding to the indicated order number. The index order number is a number from 1 to the number of index orders currently open. The index orders are arranged by the order they are opened. If an index file is closed, the index orders in it are no longer available, and index orders opened after it are moved down so there is a continuous list of index orders. Note that if an AutoOpen index exits, the index orders in it are always the first ones in the order list.
