Hi Martin,

Thanks for the examples!

Why don't you use the C# string notation that allows you to have multiple
lines of text (as in Python with the triple quote notation)?

         static void Main(string[] args) {
             PythonEngine engine = new PythonEngine();
             engine.Execute(@"
import sys
sys.LoadAssemblyByName('Embed')
import Embed
Embed.Program.Value = 20
");

Does it make any difference if you invoke Application.Run from the Python
script or from C#?
