 Note

     .  CSETCARR() is not useful in CA-Clipper.  Since this function
        was in CA-Clipper Tools and also occupies a position in CSETALL(), it
        is retained for compatibility purposes.

 Examples

     .  Switch SET UNIQUE on:

        ? CSETUNIQ(.T.)         // Returns previous setting

     .  Save a setting:

        lOldWRAP:= CSETWRAP()
