"Mastering the skills in Chapter 9, 'Writing Dynamic Code, ' will certainly boost your career as a programmer. The author introduces all the necessary components of writing a dynamic program. Initially dynamic code can look esoteric, but the author has detailed complete examples including resolved values for double-ampersand macro variables and macro arrays. Being able to see what the macro variable resolves to throughout each step will help any user grasp this concept. PROC SQL is also used in Chapter 9 as a macro variable list-generating tool, which is prevalent in most of the programs I've written. Overall Chapter 9 will convey an important message to the SAS user--that your code can have more than one dimension and can adapt dynamically to the data you are using. Until now I have not seen formal documentation to such detail on dynamic programming, and the author does a successful job of presenting this topic."
