lookup_cmd() - поиск по списку cmdlist \\
execute_command() \\
command_handler()


при обработке команд call и print вызывается функция print_command_1() из нее вызывается value_print(), а из нее - apply_ext_lang_val_pretty_printer() и c_value_print_inner()


Для тестирования
  b exec_simple_query
  print *parsetree_list
