Is it possible to make the entire program without any hard-coded parts?

Usually when we want to make a program that can be modified without re-compiling process, we read data and configurations from a file.

But this means that somewhere in the code, we must hard-code the file location of datas or config file.

For example)

public class Program
{
    public static void Main()
    {
        AppData appData = ReadAppData("app.data");
        AppConfig appConfig = ReadAppConfig("config.txt");
        Program = new Program(appData, appConfig).Run();
    }
}

In this case, two strings - "app.data" and "config.txt" - are hard-coded because it is impossible to read files without specifying the file location.

Of course, we can reduce it to one file - for example, we can read only "app.data" and get the configuration file location from that file, but we still cannot remove all hard-coded parts in our program.

So my question basically is, Is it possible to make the entire (useful) program with 0 hard-coded parts theoretically? Or in other words, Is it possible to make the entire (useful) program only with soft coding?

Please don't give me answers like "Do not do that."
