BaiPerron for VAR

[OSUPolisci]

Hello,

I would like to do a test for multiple breaks at unknown dates on a VAR equation (see Bai 2000 "Vector Autoregressive Models with Structural Changes in Regression Coefficients and in Variance-Covariance Matrices", and Qu and Perron "Estimating and Testing Multiple Structural Changes in Multivariate Regression", 2005).
How to specify the list of regressors correctly in the @BaiPerron procedure?

Many thanks for your kind help!
