Looking at old hb_InetRecvLine() I see that it can return 0, NIL, "" or character buffer and current code makes the same. Of course I can (and I think I should) change it to always return "" or errors but it's the question why the problem was not exploited by old code. Looks like socket is not in blocking mode or there is sth else exploited by recent modifications. What is your OS? best regards, Przemek _______________________________________________ Harbour mailing list [email protected] http://lists.harbour-project.org/mailman/listinfo/harbour
