Impulse response from a model object

[ashtongate]

I am trying to obtain impulse responses from a VAR using the model object. I cannot use regular VARs as I needed to enter the system in as a group of equations for a variety of reasons. I have made a model from the estimated VAR and have been able to solve it. The next step is, I assume, to use an add factor on one of the equations after setting all of the variables to zero (i.e. steady state)? Is there any way to orthognalize the impulses? Any help appreciated, thanks!

Like Ashtongate (whose August post has gone unanswered) I need to obtain impulse responses from a system object (which in this case is a VAR plus identities). This can be done in RATS, but I do not see any obvious way to do it in EViews. Can anyone indicate whether (and if so, how) this can be done in EViews. Many thanks.
