- *
- * Revision 1.2 1996/10/29 14:02:09 adam
- * Doesn't use the global data1_tabpath (from YAZ). Instead the function
- * data1_get_tabpath is used.
- *
- * Revision 1.1 1996/10/11 10:57:30 adam
- * New module recctrl. Used to manage records (extract/retrieval).

- * Changed data1 to use nmem.
- *
- * Revision 1.5 1995/12/11 09:12:52 adam
- * The rec_get function returns NULL if record doesn't exist - will
- * happen in the server if the result set records have been deleted since
- * the creation of the set (i.e. the search).
- * The server saves a result temporarily if it is 'volatile', i.e. the
- * set is register dependent.
- *
- * Revision 1.4 1995/12/05 16:57:40 adam
