In a post in May I discussed testing for cointegration in the presence of structural breaks, and provided some EViews code to facilitate this. I then followed that up with another post in June that provided corresponding R code and a set of tables, both produced with Ryan Godwin.
Riccardo (Jack) Lucchetti, co-author of the (free) gretl econometrics package converted our code into gretl script, and kindly sent it me. Passing the script on to eveyone is long overdue - sorry about the delay, Jack!
