When a queue start instruction is input, a message queue control program starts a process of asynchronous communication and allocates a queue on a memory. Messages received from a message transmitting side application are stored into the queue. When a message receiving side application requires, the messages are transferred. When a queue shutdown instruction is input, the message queue control program saves the non-transferred messages stored in the queue to a saving file. When a queue restart instruction is input, the message queue control program acquires the messages saved to the saving file and restores them to the original queue.
