This is a simple program, compiled with the Mono C# compiler, no optimisation.

Here is the original C# source code: 

<pre>
using System;

class Fibo {
	 private static int fib (int x) {
		  if (x > 1)
				return (fib(x - 1) + fib(x - 2));
		  else return (x);
	 }

	 public static int Main( String[] args) {
	 int number = 0, value;

		  try {
				number = Convert.ToInt32(args[0]);  
		  } catch (Exception e) {
				Console.WriteLine ("Input error");
				return 1;
		  }
		  value = fib(number);
		  Console.WriteLine ("fibonacci({0}) = {1}", number, value);
		  return 0;
	 }
}
</pre>

You use the program like this:

<pre>
% mono Fibo 10
fibonacci(10) = 55
% mono Fibo abc
Input error
%
</pre>

The corresponding Java source code (for bytecode decompiler tests) is in DecompilerFiboTestSource.
