+ *
+ * $Log: ir-tcl.c,v $
+ * Revision 1.17 1995-03-21 13:41:03 adam

+ *
+ * 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.
+ *
+ * Revision 1.12 1995/03/17 15:45:00 adam
+ * Improved target/database setup.
+ *
+ * Revision 1.11 1995/03/16 17:54:03 adam
+ * Minor changes really.
+ *
+ * Revision 1.10 1995/03/15 16:14:50 adam
+ * Blocking arg in cs_create changed.
+ *
+ * Revision 1.9 1995/03/15 13:59:24 adam
+ * Minor changes.
+ *
+ * Revision 1.8 1995/03/15 08:25:16 adam
+ * New method presentStatus to check for error on present. Misc. cleanup
+ * of IRRecordList manipulations. Full MARC record presentation in
+ * search.tcl.
+ *
+ * Revision 1.7 1995/03/14 17:32:29 adam
+ * Presentation of full Marc record in popup window.
+ *
+ * Revision 1.6 1995/03/12 19:31:55 adam
+ * Pattern matching implemented when retrieving MARC records. More
+ * diagnostic functions.
+ *
+ * Revision 1.5 1995/03/10 18:00:15 adam
+ * Actual presentation in line-by-line format. RPN query support.
+ *
+ * Revision 1.4 1995/03/09 16:15:08 adam
+ * First presentRequest attempts. Hot-target list.
