Revision 1.5 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 :-)
2001/05/20 Neil McCalden add planonly option
2001.09.09 Claudio Valderrama: put double quotes around identifiers
in dialect 3 only when needed. Solve mischievous declaration/invocation
of ISQL_copy_SQL_id that made no sense and caused pointer problems.
2001/10/03 Neil McCalden pick up Firebird version from database server
and display it with client version when -z used.
2001.10.09 Claudio Valderrama: try to disconnect gracefully in batch mode.
2001.11.23 Claudio Valderrama: skip any number of -- comments but only at
the beginning and ignore void statements like block comments followed by
a semicolon.
2002-02-24 Sean Leyne - Code Cleanup of old Win 3.1 port (WINDOWS_ONLY)
2003-08-15 Fred Polizo, Jr. - Fixed print_item() to correctly print
string types as their hex represention for CHARACTER SET OCTETS.
2004-11-16 Damyan Ivanov - bail out on error in non-interactive mode.
