PURPOSE:To attain the correspondence of each data at a high speed by handling the data containing each proper control number of double layer structure within a terminal equipment and a host computer and giving the conversion of function to the control number of the 1st layer with the 2nd layer having the same number for the unitary control in a mutual transfer mode of data. CONSTITUTION:The data on the graphic information, etc. which are controlled within a host computer 2 and a CRT1 are turned into a double layer structure. The 1st layer serves as discriminating information 21 to a group of data gatherings, and the 2nd layer serves as the individual information 22 under the gathering of the 1st layer 21. The different control numbers 21p and 22p are added to these information 21 and 22 and used in a unified form. When various data are transferred, the control numbers undergo the conversion of function by the communication programs of both information. The conversion functions g(x) and f(x) are used for conversion with the control number of the 1st layer against a data transfer request. While the same control number is transferred as it is with the 2nd layer.
