PURPOSE:To transmit a data independently of a system by adding the information representing the attribute of the data to the data itself to be sent in a central processing unit. CONSTITUTION:Attributes 10-12 are added to data 1, 2 are 3. The attributes include all information relevant to the data such as data length and data type (distinguishment such as hexadecimal number and BCD). Peripheral equipments receive the data and discriminate the attributes of the received data. As a result, when it is discriminated to be a BCD data, a single precision data or a double precision data, the said data is converted into an ASC II data respectively. Thus, even when the peripheral equipment side does not know the attributes defined at each area, each peripheral equipment obtains the data having the attribute according to the user's definition.
