Loading and unloading shared libraries

Progress provides several options for loading and unloading shared libraries. If you want Progress to automatically load and unload a shared library each time you invoke it, use the PROCEDURE statement without the PERSISTENT option. If you want Progress to automatically load a shared library and keep it loaded, use the PROCEDURE statement with the PERSISTENT option. To manually unload a shared library, use the 4GL RELEASE EXTERNAL statement.
