 * Revision 1.3  2000/11/22 17:07:25  patrickgriffin
 * In get_procedure_args change comment style from // to c style
 *
 * ...pat
 *
 * 2001.09.09 Claudio Valderrama: procedure's parameter names may need
 *   double quotes if they are in dialect 3 and have special characters.
 * 2001.09.21 Claudio Valderrama: Show correct mechanism for UDF parameters
 *   and support the RETURNS PARAMETER <n> syntax.
 * 2001.10.01 Claudio Valderrama: list_all_grants2() and EXTRACT_list_grants()
 *   to better organize the code that should be called to handle SHOW GRANTS.
 *
 * Revision 1.2  2000/11/18 16:49:24  fsg
 * Increased PRINT_BUFFER_LENGTH to 2048 to show larger plans
 * Fixed Bug #122563 in extract.e get_procedure_args
 * Apparently this has to be done in show.e also,
 * but that is for another day :-)
 *
 * 2003.02.04 Dmitry Yemanov: support for universal triggers
