PURPOSE:To enable a subroutine whose name to be called changes in executing to be called, by generating an information table regarding the entry name and the entry point of the subroutine having possibility to be called in executing, at time of linking, and perform the call of the subroutine by retrieving the table and obtaining the information of the entry point at time of calling the subroutine. CONSTITUTION:A linking means 1 inputs and links an object module including its entry by designating clearly a required entry name at time of linking, and generates an entry name table having the information of a designated entry name and the entry point corresponding to the entry name in a generated load module. A dynamic subroutine call means 22 retrieves the entry name table generated by the linking means 1 at time of linking, at time of calling the subroutine, and obtains the information of the required entry point, and calls the subroutine according to the information. In such way, it is possible to call the subroutine whose name to be called changes under an executing environment not being provided with a dynamic linking function.
