Utilizing modern computer languages, economic researchers and students can obtain maximum flexibility, portability, intellectual satisfaction, and sound research techniques by employing the computer on‐line and interactively without relying on canned programs like SPSS, TSP and other “black boxes”. The author exploits this method in research as well as in classes from principles to econometrics. The power of new languages is illustrated with APL for two economic applications: (1) construction of GNP indexes from price and quantity data, and (2) a multiple regression model. The latter, including coefficient estimates, predicted and actual dependent variables, individual errors, and the sum of squared residuals, takes one short line of code.
