Tim series Analysis in EViews

Hello Everyone,I have a question which may be very simple .For Example I have estimated ARIMA(1,1,4) from a data having sample 1961-1999.To produce forecast I re-estimate sample from 1961-1995 and then its easy to produce forecast on eviews.I want to confirm forecast produced by EViews manually but I am not able to do so.Anyone can guide me.
