Adding new Currency for FX Forwards

I want to book trades in a new currency say ANC. I have followed instructions given in
http://developers.opengamma.com/docs/user-guides/curves-currencies
and could get numbers for IR Swaps in a new currency ANC. However I could not get numbers for FX Forward contracts. Can anyone guide me how to get PV in case of ANC/USD FX Forward contracts? Do I need to change any standard function definition?
