PURPOSE:To improve the operability of an application program by preliminarily registering and storing a terminal input data image in a host computer and transferring this image to the terminal side at the time of a data input request from the application program on the terminal side. CONSTITUTION:When data input is requested from an application program part 3 on the terminal side, a terminal input/output switching means 2 sends dummy data to a host computer 20. An input data generating means 5 reads in one data from a terminal input data image storage means 7 and transfers it to a program part 6. The program part 6 sends the terminal input data image to a terminal equipment 10 together with the discrimination result of normalcy or abnormality. The switching means 2 transfers data to the program part 3 when data is correct. If data is wrong, the input request is transferred to a terminal input means l to execute the data input request from the program part 3. |
