Description

ORDKEY() is an Order management function that returns a character expression, cExpKey, that represents the key expression of the specified Order.

You may specify the Order by name or with a number that represents its position in the Order List. Using the Order name is the preferred method.

The active RDD determines the Order capacity of an Order Bag. The default DBFNTX and the DBFNDX drivers only support single-Order Bags, while other RDDs may support multiple-Order Bags (e.g., the DBFCDX and DBFMDX drivers).

      USE Customer NEW via _DBFCDX
      INDEX ON  Customer->Acct  ;
         TO  Customer           ;
         FOR Customer->Acct > "AZZZZZ"
      Index on Custumer->Id to Cusid

      ORDKEY( "Customer" )      // Returns: Customer->Acct
      Set order to 2
      ORDKEY()                  // Returns: Custumer->Id
