In a screen display control of a terminal effecting screen display through communications with a host computer via a communication line, there are provided on the terminal side a file in which screen data to be frequently used is subjected to a download or is loaded and a reference table to which a systematic correspondence list associated with display screen data, screen selection data, and next screen data is registered. When screen data being displayed on a display of the terminal is already registered as display screen data to the reference table, if screen select data is inputted, the next screen data registered in association with the corresponding display screen data and the input select data is retrieved from the reference table so that the next screen data is extracted from the screen data file so as to be displayed on the display. When the screen data being displayed is missing in the reference table, in response to an input of the next screen select data, the input data or information associated therewith is transmitted to the host computer so as to request for the next screen data or information specifying the next screen data.
