Abstract

Code generation is very complex. Using ALGOL68, complexity increases due to the recursivity of the manipulated values. The set of routines manipulating values will be recursive too. Describing such a manipulating process with flow charts makes it less readable. To avoid that difficulty the description of the process will use a generative action grammar. With such a grammar recursivity is natural, so the description of a recursive process will be very readable. Moreover, such a grammar can easily be translated into a program, which will be very structured and modular. The produced code will be very structured too and that can be helpful for debugging and checking processes.
