In the new code you are creating one instance of G which you seed with 1234 and then calling expovariate on it each time you call main without reseeding. You're only seeding it once and reusing it, so you would get different values. What you had before, where you seeded G.Rnd in the main was fine. I also suggest you change one thing at a time, rather than reworking large parts each iteration. All I was suggesting was a simple print statement in the Run method like you had it before -- ./Sven
