PURPOSE:To decrease the number of syntax structure rules and also to omit the buffer control description in the rule by providing a buffer selecting part. CONSTITUTION:A buffer selecting part 16' selects a buffer that starts a rule set out of those buffers in the state selected by a state selecting part 16. An analysis rule processing part 17 carries out the rules of nodes in all selected buffers. Then the part 16' selects an executing buffer and starts the rule sets of all selected buffers. Thus it is possible to decrease the number of syntax structure rules and to omit the description of buffer shift in the rule.
