Online tester commands can be used to simulate an application program startup request. When a UAP requests startup of an application program, the application program does not actually start, but the data to be passed is saved in an MCF send message file created by the online tester. To send this data and start the application program, the user enters an online tester command to download the data to another file. Then, the user starts the application program by command input, using this file as the MCF receive message file. In this way, a startup request can be simulated for an application program that was not actually started by the UAP.

Figure 2-9 outlines simulation of an application program startup request.
