Once you have successfully built your application, you can run it from the Application Builder.
If the application can run without arguments you can run it by choosing Works > Build > Run or clicking the toolbar button.
If the application requires command line arguments, or you want to see what it writes to the standard output, or you need some other setups, choose Works > Build > Run With Arguments or click the toolbar button. This raises a dialog, shown in The Run With Arguments dialog below.
The Run With Arguments dialog also allows you to set a different file to execute, rather than the saved image. This is useful if your application needs some setups, or if it needs to be invoked by some other program (for example, when it is a dynamic library).
To kill just one such process choose Works > Build > Kill Application or click the dropdown to the right of the button. This raises a menu listing the invoked applications that are still running in the chronological order in which they were invoked. Select one item from the menu to kill that process.
