54 * Revision 1.8 1995/05/11 14:03:57 adam
55 * Changes in the reading of qualifier(s). New function: ccl_qual_fitem.
56 * New variable ccl_case_sensitive, which controls whether reserved
57 * words and field names are case sensitive or not.
59 * Revision 1.7 1995/04/17 09:31:46 adam
60 * Improved handling of qualifiers. Aliases or reserved words.
62 * Revision 1.6 1995/02/23 08:32:00 adam
65 * Revision 1.4 1995/02/14 19:55:12 adam
66 * Header files ccl.h/cclp.h are gone! They have been merged an
67 * moved to ../include/ccl.h.
68 * Node kind(s) in ccl_rpn_node have changed names.
70 * Revision 1.3 1995/02/14 16:20:56 adam
71 * Qualifiers are read from a file now.
73 * Revision 1.2 1995/02/14 10:25:56 adam
74 * The constructions 'qualifier rel term ...' implemented.
76 * Revision 1.1 1995/02/13 15:15:07 adam
77 * Added handling of qualifiers. Not finished yet.
