You can change it in the RDD source and remove the RTE call but for CDX is very bad idea. In CDX format key expression type is not stored inside index header file and can be determinated only by key evaluation. Without expression type RDD will not know how to convert keys for some operations like seek so they can give incorrect results. > I must often read existing bases and indexes.

Try the example I sent with ordKeyVal() using current SVN Harbour code. It shows that keys in index are not stored directly but modified by not revertible function. See in MSDN what LCMapString() with LCMAP_SORTKEY does in Windows. best regards, Przemek _______________________________________________ Harbour mailing list Harbour@harbour-project.org http://lists.harbour-project.org/mailman/listinfo/harbour
