7 * Revision 1.15 1999-10-21 12:06:29 adam
8 * Retrieval module no longer uses ctype.h - functions.
10 * Revision 1.14 1999/08/27 09:40:32 adam
11 * Renamed logf function to yaz_log. Removed VC++ project files.
13 * Revision 1.13 1998/10/13 16:09:52 adam
14 * Added support for arbitrary OID's for tagsets, schemas and attribute sets.
15 * Added support for multiple attribute set references and tagset references
16 * from an abstract syntax file.
17 * Fixed many bad logs-calls in routines that read the various
18 * specifications regarding data1 (*.abs,*.att,...) and made the messages
19 * consistent whenever possible.
20 * Added extra 'lineno' argument to function readconf_line.
22 * Revision 1.12 1998/02/23 10:57:09 adam
23 * Take care of integer data nodes as well in conversion.
25 * Revision 1.11 1998/02/11 11:53:35 adam
26 * Changed code so that it compiles as C++.
28 * Revision 1.10 1997/09/30 11:50:04 adam
29 * Added handler data1_get_map_buf that is used by data1_nodetomarc.
31 * Revision 1.9 1997/09/24 13:35:45 adam
32 * Added two members to data1_marctab to ease reading of weird MARC records.
34 * Revision 1.8 1997/09/17 12:10:37 adam
37 * Revision 1.7 1997/09/05 09:50:57 adam
38 * Removed global data1_tabpath - uses data1_get_tabpath() instead.
40 * Revision 1.6 1997/09/04 13:51:58 adam
41 * Added data1 to marc conversion with indicators.
43 * Revision 1.5 1997/09/04 13:48:04 adam
44 * Added data1 to marc conversion.
46 * Revision 1.4 1996/03/25 10:18:03 quinn
47 * Removed trailing whitespace from data elements
49 * Revision 1.3 1995/11/01 16:34:57 quinn
50 * Making data1 look for tables in data1_tabpath
52 * Revision 1.2 1995/11/01 13:54:48 quinn
55 * Revision 1.1 1995/11/01 11:56:08 quinn
56 * Added Retrieval (data management) functions en masse.
