eliminate global global_command variable * toplev.h, toplev.cc (global_command): Delete. * parse.h, oct-parse.in.yy (octave_parser::stmt_list): New member variable. (octave_parser::octave_parser): Initialize it to zero. (octave_parser:~octave_parser): Delete it. (octave_parser::reset): Delete it and set it to zero. * toplev.cc (main_loop): Use curr_parser->stmt_list instead of global_command. * input.cc (get_debug_input): Likewise. * oct-parse.in.yy (eval_string, parse_fcn_file): Likewise. (ABORT_PARSE): Don't set global_command to zero. (input): Set curr_parser->stmt_list instead of global_command.
