Eviews regression analysis

The current account will be used as the dependent variable for a quarterly data analysis from 1970-2014. The analysis should be divided : 1970q1-1986q4, 1987q1-1998q4 and 1999q1-2014q4. You should employ the methodology, which will include a multiple Bai Perron test, perform regression analysis and interpret the results. Moreover, i want the commands from the Eviews the end. Thank you.
