*
* FULL DESC:
*
* This is an example command mode application that will indicate when
* a SoftLogix5800 controller changes modes. It uses the new Outbound
* Event support that is being introduced with version 12 of the
* SoftLogix5800 product.
*
* It should be compiled using the Microsoft Visual Studio compiler.
* You can use the following steps to compile and run this example.
*
* 1) Open a Windows command prompt window by choosing
* Start->Run, and entering cmd for the command line.
* 2) Make sure that the Microsoft Visual Studio compiler bin
* directory is in your path.
* 3) Execute the compiler using the following command
* cl OutBoundEventExample.cpp
* 4) Run the resultant executable using the following command
* OutBoundEventExample 3
* The 3 in the example above indicates the slot number for
* the controller for which you want to monitor mode changes.
*
* This example code waits for the controller mode change event,
* and after receiving the mode change event, checks the controller
* mode events to determine and display the new controller mode.
