If you are writing an application or game that allows starting with special parameters on the command line, you can use this command to retrieve the parameters.

|
For example, you might want to start the program with a debug variable set so you can track stuff during execution. So, you could offer the ability to run the executatble with a /debug parameter. If they execute the program with the parameter, then you can set a flag inside your game.
