PURPOSE:To finish the issuing frequency of a receive macroinstruction done by an applied program at once by securing such constitution where a communication access processing part performs a writing action on its own buffer area and sets a data input area of the applied program in response to the scale of reception data. CONSTITUTION:The reception data given from a terminal 1 is written on its own buffer area 9 via a communication access processing part 6 of a data processor 5. The scale of the reception data can be easily known. Then a data input area 11 is set most properly to a user area 10 in accordance with the scale of the reception data. The data given from the terminal 1 are written on the area 11 just with a single receive macroinstruction given from an applied program 7.
