------------------------------------------------------------------------------
 Prototype

     ERRCODE recno(
                    WORKAREAP wa,
                    ITEM record
                  )

 Arguments

     wa is a pointer to self.

     record is a pointer to an Item that determines the
     current row identifier, and will normally be a number
     indicating the row number.

 Description

     Retrieves the physical row identifier at the current workarea
     cursor position for use by the CA-Clipper runtime system.  If
     your driver operates on a database that does not contain record
     numbers, you must provide a unique value to be used to identify
     each row.

 Default Behavior

     You must implement the default behavior of this method through a
     subclass.

 Implementation Notes

     .  If your RDD supports relations, update them with a forceRel()
        prior to attempting relative movement.
