PURPOSE: To enable each terminal to carry out the data processing with no limitation received to its own memory capacity in regard of a data processing execution system in a data processing system where plural terminals connected to a network carry out the data processing based on the control processing of a control program.
CONSTITUTION: A basic control program 30 included in a control program is resident in a primary memory 20 of each terminal 2. Meanwhile the non-basic control programs 31 are dispersedly eveolved in e secondary memory 21 of each terminal 2. In such a constitution, each terminal 2 loads the necessary program 31 to the memory 20 from the memory 21 for execution of the data processing. At the same time, the terminal 2 acquires the programs 31 which are not eveolved yet in the terminal 2 itself from the terminals of the controller side and then loads these programs 31 for execution of the data processing.
