PROBLEM TO BE SOLVED: To easily add, as a single body, function modules that a plurality of programs can use in common. SOLUTION: A loader part 122 is provided with a function of loading an application and function modules. A newly loaded application is stored in an application storage part 133 and a newly loaded function module is stored in a function storage part 134. A function table TB showing the correspondence relation between the function names of loaded function modules and their actual addresses is generated in a function table storage part 135. A function call is made by the application by recognizing an actual address by referring to the function table TB. The function modules are called even by an OS program and other function modules.
