C# – How to start a program with arguments when debugging

I want to debug a program in Visual Studio 2008. The problem is that it exits if it doesn't get arguments. This is from the main method:

if (args == null || args.Length != 2 || args[0].ToUpper().Trim() != "RM") 
{
    Console.WriteLine("RM must be executed by the RSM.");
    Console.WriteLine("Press any key to exit program...");
    Console.Read();
    Environment.Exit(-1);
}

I don't want to comment it out and and then back in when compiling. How can I start the program with arguments when debugging? It is set as the StartUp Project.
