# Export for Runner

Export for Runner.. saves to disk a copy of your model in a format that can be read by the Commercial Runtime version of the software. The Commercial Runtime version of the software takes control of the computer screen - title bars, menus, scroll bars, window controls and tool bars will be blackened out. As a result, you as an author can control user access to the various components of the model and interface.

When you choose Export for Runner, you will first encounter a dialog which enables you to select a target screen size. Choices are 640x480, 800x600, 1024x768, and 1280x1024. In addition, you can elect to hide or show the Windows task bar. Make your choices, and then hit OK to export your model to disk. The extension for STELLA Commercial Runtime is .str.

The Commercial Runtime version is an excellent vehicle for the commercial distribution of your work. For details on commercial licensing, contact HPS directly. To facilitate your work in the development of flight simulators and learning laboratories, we have included a developer's copy (i.e., not for distribution) of the Runtime software.
