Abstract

PURPOSE:To reduce the number of key inputting operations by storing changed control circuit data in a changed data registration buffer together with shortened characters defining the changed control circuit data after transferring the registered content of a registration buffer to a circuit data editing means where the data to be changed are changed. CONSTITUTION:When part of control circuit data registered in a registration buffer 5 is changed, the registered content of the buffer 5 is shifted to a circuit data editing means 2a and the control circuit data, the registered content of which is to be changed, are changed, the circuit data are stored in a changed data registration buffer 6 together with shortened characters defining the changed control circuit data. When the stored data are read out, the data are designated by using the shortened characters. Therefore, data changing operations are simplified, because it becomes unnecessary to input all of the registered control circuit data again and data to be changed can be changed by only performing changing operations on the data.
