 relText()
 Obtain the character expression of the specified relation
------------------------------------------------------------------------------
 Prototype

     ERRCODE relText(
                          AREAP wa,
                          USHORT relNum,
                          BYTEP cExpr
                       )

 Arguments

     wa is a pointer to self.

     relNum is a numeric value that specifies for which relation the
     character expression is to be obtained.

     cExpr is a pointer to a buffer that contains the character
     expression of relation relNum.

 Description

     relText() obtains a string that describes the relationship of the relNum relation
     to the work area referenced by wa.  relNum is a one-based number.

 Default Behavior

     relText() implements the behavior of the CA-Clipper function
     DBRELATION().  It scans relations for the work area referenced by wa
     and returns the key text for the child work area.

 Implementation Notes

     .  If this method is reimplemented, be careful to return the key
        text for the relation at relNum-1 since relNum is a one-based number.
