PURPOSE:To attain the selection of types of forbidden rule processes by one sentence processor by providing a key which indicates the type of a forbidden rule process, a storage device which stores information showing the type of an indicated forbidden rule process, and a controller which can carry out plural forbidden rule processes. CONSTITUTION:Data inputted by a key 101 and showing the type of a forbidden rule process are allocated to each bit in the form of flag information and stored in a storage device 102. A controller 103 refers to said data to decide the pres ence or absence of an forbidden rule process. When a forbidden rule process is carried out, it is decided whether or not a hung-down forbidden rule process is carried out in the next step. If not, it is decided whether a send-out forbidden process is carried out or not in the next step. If not, it is decided whether other forbidden processes are carried out or not in the next step.
