   Using RDDs in your Applications
------------------------------------------------------------------------------

   When an Advantage RDD is linked into your application, the Advantage
   RDD can be used in three ways:
        1) as the default RDD,
        2) as the preferred RDD with an alternate RDD, or
        3) accessible on an as-needed basis.

   Advantage as Default RDD
   To make the Advantage RDD the default RDD for your application, use
   either the function AX_SetRDD() or RDDSetDefault().

   Preferred and Alternate RDD
   The Advantage RDD may be set as the preferred RDD and a non-Advantage RDD
   may be set as the alternate RDD. The Advantage command AUTOUSE
   provides this capability. The AUTOUSE command works like the CA-Clipper
   USE command. The Advantage RDD will be used in the work area if the
   table specified in the AUTOUSE command is located on a server
   where the Advantage server is running. If the table is
   not located on a server where the Advantage server is running,
   the alternate RDD is used for the work area.

      AUTOUSE test.dbf VIA "DBFNTXAX" ALTERNATE "DBFNTX"

   As-needed RDD
   To access an RDD which is not the default on an as-needed basis, use
   the VIA clause in your USE command. For example, if DBFNTX is the default
   RDD, you can access the Advantage NTX RDD as follows:

      USE test.dbf VIA "DBFNTXAX"

   If the Advantage RDD is the default RDD, you can access DBFNTX or
   another RDD as follows:

      USE test.dbf VIA "DBFNTX"
