Correct classes for options on commodity futures?

[Ken Anderson-2]

I need to generate greeks and implied volatilities for options on  
commodity futures.  Right now, I'm using BlackScholesProcess and  
VanillaOption.  Is that correct?  I would like to use Black-76, but  
I'm not sure if I'm getting that this way or not...

Thanks,
Ken

If I'm not mistaken, you'll get the Black-76 formula if you set the  
cost of carry to 0, i.e., if you pass to the constructor of the process  
a dividend yield equal to the risk-free rate.

Right now I'm doing this:

FlatForward flatDividentTS = new FlatForward(todaysDate, 0.0, fixed365);

Should I make it the same as the risk free rate?  So like 4.5% right now?

Thanks again,

Ken

Based on Haug, p. 7, I would think so.
