+ * Revision 1.17 1995-03-21 13:41:03 adam
+ * Comstack cs_create not used too often. Non-blocking connect.
+ *
+ * Revision 1.16 1995/03/21 08:26:06 adam
+ * New method, setName, to specify the result set name (other than Default).
+ * New method, responseStatus, which returns diagnostic info, if any, after
+ * present response / search response.
+ *
+ * Revision 1.15 1995/03/20 15:24:07 adam
+ * Diagnostic records saved on searchResponse.
+ *
+ * Revision 1.14 1995/03/20 08:53:22 adam
+ * Event loop in tclmain.c rewritten. New method searchStatus.
+ *
+ * Revision 1.13 1995/03/17 18:26:17 adam
* Non-blocking i/o used now. Database names popup as cascade items.
