Comparing Coefficients in Different Regression Models

Prompted by a question (here) on Statalist relating to efforts to compare (with a TTest) whether coefficients in two separate regression models systematically differ I stumbled upon the suest command. With the suest command, one can, e.g., regress one model, store its results, regress a second model, store its results, and then compare them with the test command. "This will yield a chi2 statistic with 1 degree of freedom. You can run this for each variable." This will help one assess whether the coefficients are the same in each regression model or not.
