PURPOSE:To make the physical structure and logical calling structure of a program independent, by solving the corresponding between a load module and the program at the time of compiling. CONSTITUTION:When a load module is called, the calling side program obtains an objective routine address based on the address of the called load module control unit and that of a control section table. When the load module is not loaded into a virtual storage device at this time, the control is handed over to a dispatching routine and, after the load module is loaded into the virtual storage device, the objective routine is called. When the processing is a static connection, the objective routine is directly called, because the routine is already loaded. Moreover, it is possible to realize the same function as overlay by utilizing the counter of the load module control unit.
