+ * Revision 1.27 1995-05-11 15:34:47 adam
+ * Scan request changed a bit. This version works with RLG.
+ *
+ * Revision 1.26 1995/04/18 16:11:51 adam
+ * First version of graphical Scan. Some work on query-by-form.
+ *
+ * Revision 1.25 1995/04/17 09:37:17 adam
+ * Further development of scan.
+ *
+ * Revision 1.24 1995/04/11 14:16:42 adam
+ * Further work on scan. Response works. Entries aren't saved yet.
+ *
+ * Revision 1.23 1995/04/10 10:50:27 adam
+ * Result-set name defaults to suffix of ir-set name.
+ * Started working on scan. Not finished at this point.
+ *
+ * Revision 1.22 1995/03/31 10:43:03 adam
+ * More robust when getting bad MARC records.
+ *
+ * Revision 1.21 1995/03/31 08:56:37 adam
+ * New button "Search".
+ *
+ * Revision 1.20 1995/03/29 16:07:09 adam
+ * Bug fix: Didn't use setName in present request.
+ *
+ * Revision 1.19 1995/03/28 12:45:23 adam
+ * New ir method failback: called on disconnect/protocol error.
+ * New ir set/get method: protocol: SR / Z3950.
+ * Simple popup and disconnect when failback is invoked.
+ *
+ * Revision 1.18 1995/03/21 15:50:12 adam
* Minor changes.
