Billions of lines of code that have been written in Cobol, PL/I, and other old programming languages are still in active use. Many commercial efforts to convert these to more modern languages have begun, but few have succeeded. These authors discuss the nuts and bolts of conversion between several pairs of languages and some of the possibilities and limitations of automating language conversion.
