I have seen how useful has been -w3 to detect bad code like: function lookup ..... cOldAlias = alias() select cNewAlias ..... <miss to restore the saved alias> return I understand it could also warn valid code but I still think it could be useful to have it maybe as separate switch like ( -w3U or -wu ) to detect "possible" rt errors. Clearly typed vars would be a more definitive solution but it also will require a big change in the code, instead this could be a "run once" switch to use with -w3 to clean and check existing code. best regards, Lorenzo so it could be also useful to check where giving a look but now after deleting many unused assignments _______________________________________________ Harbour mailing list Harbour@harbour-project.org http://lists.harbour-project.org/mailman/listinfo/harbour
