George,

 When I see abrupt questions like this with no context (on any listserv), I often wonder (nervously) how much background reading the poster has done on the statistical method being applied, in this case, cointegration. I could be wrong -- perhaps you fully the rationale for the procedure and just want the specific Stata syntax, which I imagine you could have found yourself with a bit of searching. Anyway, it's not just a one-liner that someone can copy into an email, especially without knowing anything about your model. I think you're going to have to do the programming yourself. To that end, have a look at:

Johansen, S. (1995). Likelihood-Based Inference in Cointegrated Vector 
Auto-Regressive Models. Oxford, UK: Oxford University Press.


Prazmowski, P. (2005). A recursive cointegration test using the Kalman filter and its application to fiscal equilibrium in the Dominican Republic.
Applied Economics Letters, 12(3), 155-160.

My two cents,
