This book--both learning tool and handy reference guide--provides the information you need to learn this powerful way of coding.

    Although free-format information is available in IBM manuals, it is mixed in with everything else, requiring hours of tedious research to track down the information you need.

He methodically covers the "how to" involved in free-format RPG IV, including many style issues, such as named indicators and built-in functions. He also addresses input and output, program flow, data manipulation, and math operations--plus prototyping and APIs.

    Free-format RPG now encompasses nearly all functional aspects of the language, and this Third Edition of Free-Format RPG IV brings you up-to-date on all the latest features.
